First Announcement (pdf 152 KB)


The aim of this Workshop is to keep the scientific community working on nonlinear phenomena in lasers, optics and photonics in general updated with the most recent developments and tendencies in the field. We hope that the Workshop will provide the opportunity to interchange ideas in a relaxed environment, contributing in this form to the development of new scientific collaborations. Emphasis will be put in the participation of Latin-American scientists.


The topics covered by the Workshop include, but are not limited to:


Lasers: General laser theory; Semiconductor lasers; Microcavity and microdisk lasers; Photonic crystal lasers; Laser design and operation; Dynamical laser instabilities; Noisy laser behavior; Spatial pattern formation; Laser applications; Laser spectroscopy.


Nonlinear optics: Phase conjugation; Beam trapping, self-focusing and defocusing; Self-phase modulation; Optical frequency converters; Optical bistability, multistability, and switching; Dynamics of nonlinear optical systems; Optical instabilities, optical chaos and complexity; Optical spatio–temporal dynamics; solitons; nonlinear guided waves and waveguides.


Optical materials and nanophotonics: Nonlinear optical crystals; Photorefractive and semiconductor materials; Photonic bandgap materials; metamaterials and plasmonics; Nonlinear behavior in nanophotonics.

The workshop proceedings will be published as an IEEE Conference Proceeding within the IEEE Conference Publications Program (CPP) and will be included in the IEEE Xplore database. CPP will handle the worldwide post-conference distribution, assuring wide distribution of the conference proceedings by providing abstracting and indexing of all the papers for inclusion in worldwide databases.


Manuscripts should be submitted as IEEE Xplore-compatible PDFs.

Submission to the Conference Proceeding will be open from October 1, 2011 to December 6, 2011. Papers should be prepared online using the IEEE PDF eXpress service, and submitted online as IEEE Xplore-compatible PDFs.  A minimum of 2 pages is required. Please follow these instructions to submit your manuscript:


1) Access the IEEE PDF eXpress site at

2) Create a new account and login using the following Conference ID: colonia11wkxp

3) Access Article Templates on the left menu. MS Word and LaTeX templates incorporate the specifications for conference proceedings articles on either a US-letter or an A4 page size.

4) Once the PDF file is generated, compatibility with IEEE Xplore-PDF can be checked by clicking “Submit PDF for Checking”. You can also convert files using “Submit Source Files for Conversion”.

5) You will receive online and email confirmation of successful upload. If you submitted a PDF for Checking, the email will show if your file passed or failed.

6) Repeat this process until your file passes the PDF Check.

7) When you have an acceptable IEEE Xplore-compatible PDF, approve this final PDF to the conference.




The Workshop will be held in Colonia del Sacramento, Uruguay, at the Radisson Hotel. Colonia del Sacramento was founded in 1680 by the Portuguese, and it was declared World Heritage site by UNESCO in 1995. Located on the north bank of the Rio de la Plata estuary, upriver from Montevideo, Colonia del Sacramento is situated at the tip of a peninsula. The historic quarter of the city, with the towers of the Church of the Holy Sacrament and the lighthouse, constitutes a remarkable testimony, in its plan and its monuments, to the character and the objectives of a European colonial city at the end of the 17th century.


Hotel information


The workshop will take place at the Radisson Hotel of Colonia del Sacramento (W. Barbot 283). The hotel is conveniently located by the River Plate (see map), one block from the historic part of the city, and it has a panoramic restaurant, a lobby bar, an outdoor swimming pool overlooking the River Plate, two hot baths and a Jacuzzi tub.


To make your reservation, please contact the Hotel Radisson directly, indicating your arrival and departure days, accompanying person if any, and mention "Laser and Optics Workshop participant". Contact information:


Please make your hotel reservation as soon as possible as it could be very busy due to a long holiday weekend in Argentina.

In front of Hotel Radisson there is a nice budget hostal: Posada del Rio (W. Barbot 258) which is a good option for more economic accommodation in single and double rooms with private toilets.


Special rates for the Workshop participants are (per room per night including breakfast, in superior or standard category, depending on availability):

Single room occupancy, U$S 117

Double room occupancy, U$S 130


Arrival information


Colonia del Sacramento is located in the coast of the Rio de la Plata estuary, about 1 hour by boat from Buenos Aires (Argentina), and about 2 hours by bus (177 kilometers) from Montevideo (Uruguay).


·       By Boat


From the Buenos Aires port Buquebus has daily ferries to Colonia del Sacramento (US$20, 2½ hours) and high-speed buque-aviones (US$35, one hour). If you flight to Buenos Aires, a bus or a remiss with Manuel Tienda Leon will take you from the airport to the port, where you can then take the boat to Colonia del Sacramento. The hotel is a 15 min. walk from Colonia port (see map), and there are plenty of taxis at the port waiting for the boats that arrive from Buenos Aires.


·       By Bus


An alternative way is to fly to Montevideo, Uruguay. From the airport take a taxi (about 50 dollars, 20 minutes) or a bus (about 30 pesos uruguayos, 40 minutes) to the main bus station in downtown Montevideo, 'TRES CRUCES', where you can catch a bus to Colonia del Sacramento (about 10 dollars, there are frequent buses of various companies as COT –see below for more information). The bus takes about 2 hours to arrive to Colonia del Sacramento, in Colonia del Sacramento the bus terminal is also within walking distance to the Radisson Hotel (see map) and there are taxis waiting for the buses arriving from Montevideo.


Currency: The local currency is “pesos uruguayos: You can change money at the airport. Also, notice that is an English-speaking tourist information office at the airport.




When you exit the airport, you will find a bus station right in front of the arrival terminal. Take the brown and orange bus of the COPSA company ( that says ‘MONTEVIDEO’ at the front. The bus runs about every 15 minutes. Ask the bus driver if the bus stops at TERMINAL TRES CRUCES to be sure. It will stop at the corner of the bus station (“Goes” and “Acevedo Dias” streets). You have to buy the ticket in the bus. The bus ticket costs about 2.5dollars (30 pesos uruguayos), the bus driver will only take pesos uruguayos currency. During rush hour the bus from the airport to the bus station can take about 1 hour. If you prefer to take a taxi from the airport to Tres Cruces, then is safe to take a taxi and there will be taxis at the airport exit. The cost is approximately 50 dollars.


From TRES CRUCES there are frequent buses to Colonia. Bus timetable:

History of the ‘Rio de la Plata’ Workshop


The first and second workshops were held in Colonia del Sacramento, in December 2003 and 2005; the third workshop was held in Punta del Este (Uruguay) in December 2007, and the fourth workshop, in Piriapolis (Uruguay) in December 2009.


These workshops were sponsored by the Optical Society of America (OSA), the Photonics Society, the Air Force Office of Scientific Research (AFOSR), the Office of Naval Research Global (ONRG), and the Commission on Quantum Electronics of the International Union of Pure and Applied Physics (IUPAP).


The proceedings of the 4th Workshop were published in a Topical Issue of the European Physical Journal D.
