Workshop Description:
The Future of SOAs:
Semiconductor Optical Amplifiers (SOAs) have been a topic of intense research for over twenty years. Although SOAs have lower saturation powers than fiber amplifiers, they are most unique because they cover the whole spectral range from 1300 to 1600 nm with sufficient gain for most access and medium-haul applications. A recent router introduced by startup Infinera clearly exploits SOAs not only to boost signal power but also demonstrates the benefit from the monolithic integration of SOAs with other InP based materialsain.
High nonlinearity of SOA is most unique among all known optical materials - it has led to the development of a new class of commercially available nonlinear all-optical products. This includes wavelength conversion where data on a signal at wavelength l1 is converted to data at another wavelength l2. Optical demultiplexing where a very high speed ( > 100 Gb/s) optical data is converted to several tributaries of low speed ( ~ 10 to 20 Gb/s) data for information retrieval using conventional electronic means. Optical clock recovery where a clock signal (timing signal which determines the positions of the 1`s and 0`s ) are generated from the high speed optical data signal. SOA is also suitable for many all optical processing applications such as label swapping, optical header recognition and optical switching. All-optical signal processing is expected to become increasingly important in future ultrahigh capacity telecommunication networks. The development of all optical logic technology is important for a wide range of applications in all optical networks, including high speed all optical packet routing, and optical bit pattern recognition. Recently SOAs have found new applications for FTTx and non-telecommunications fields, which has triggered a new interest in the technology.
After a short introduction on the theory and concepts behind SOAs including new materials such as Quantum Dots, we will discuss recent trends in industries and highlight new applications not only in the field of telecommunications but also in the field of medicine and related fields.
The workshop organizers are , University of Karlsruhe, Germany & Prof. Dr. N. K. Dutta, University of Connecticut, USA and author of a new book on "Semiconductor Optical Amplifiers". Both of the workshop organizers have worked for many years with SOAs, both in the industries and at the university and have generated well over 100 publications in the field.

K. Morito, Fujitsu, JapanBiographyKen Morito was born in Saitama Prefecture, Japan, in 1964. AbstractI will introduce our 1550 nm polarization-insensitive SOAs with high-power and low-noise characteristics which we have developed for linear applications such as broadband optical amplifiers and optical gate switches. Our polarization insensitive strained-MQW SOA chip exhibited a high fiber-coupled saturation output power of +20 dBm and a low fiber-coupled NF of 6.0 dB with a low PDG of 0.6 dB. Additionally our polarization insensitive SOA module applying a polarization-sensitive MQW SOA chip in a polarization diversity configuration exhibited a high saturation output power of +22 dBm and a low NF of 5.7 dB with a low PDG of 0.5 dB.

B. Sartorius, HHI, GermanyBiographyBernd Sartorius studied physics in Frankfurt and Berlin. He received his PhD from the Technical University of Berlin in 1982. He then joined the Heinrich-Hertz-Institute for Telecommunications, where he first worked on optical techniques for characterisation of semiconductors. In 1991 he became head of a technological project developing semiconductor optical amplifiers. He focussed the project work on devices for all-optical signal processing. Novel (patented) types of multi-section lasers/amplifiers were developed and applied especially for clock recovery and decision in all-optical 3R signal regenerators. Presently Dr. Sartorius is head of projects that cover the whole range from design and technology of semiconductor devices up to system experiments on high speed all-optical signal processing. AbstractIn SOAs the amplification process deplets the carrier density, and that saturates the gain after a certain light path. Commercial devices designed for linear amplification thus have lengths below 1 mm. In this contribution we discuss the potential of ultra-long SOAs (2…8mm ) for high speed all-optical processing applications. Novel physical effects (Two Wave Competition) are presented and the improved efficiency of optical nonlinearities is pointed out.

L. Zhang, Lucent, USAAbstractThe effect of p-type doping of the active region of multiple quantum well semiconductor optical amplifiers has been studied. Spectrogram measurements of the dynamics of the SOAs reveal that both gain and phase recovery times have been significantly reduced by the p-doped barriers of multiple quantum wells. 1/e Phase recovery time as short as 11 ps is demonstrated using this approach.

Dr. Zyskind is an OSA Fellow and was the 2001 Technical Program Co-Chair and 2002 General Co-Chair of the Topical Meeting on Optical Amplifiers and Their Applications. AbstractOptical communications provides the largest and most important market for optical amplifiers. Erbium-doped fiber amplifiers revolutionized optical communications by enabling economical high capacity systems. EDFAs are the boosters, repeaters and preamplifiers of choice for a wide range of optical communications systems and are massively deployed. Commercial Raman amplifiers are now available and their deployment is growing rapidly because of their recognized value for reducing network costs. The extent to which SOAs will challenge the primacy of fiber amplifiers in these important applications will depend on their ability to better meet the cost and performance requirements.
