2/spl times/2 all-optical exchange-bypass switch
- Trang TuC3-TuC3
We demonstrate an optically addressable 2/spl times/2 exchange-bypass switch operating with 10 Gbps data packets. Switching is achieved in an optical amplifier gate and the performance of the device is independent of packet length and content.

GaAs-based tunnel junctions for micro-cavity devices
- Trang MH5-MH5
The development of high quality GaAs-based tunnel junctions grown by MBE was systematically studied. Fabricated Si/Be-doped GaAs tunnel junctions show record low junction resistance. The enhancement of lateral current spreading is demonstrated.

1.3 micron InGaAsN oxide-confined VCSELs grown by MOCVD
- Trang TuH3-TuH3
Summary form only given. An Emcore D 180 metalorganic chemical vapor deposition (MOCVD) system was used to develop 1.3 micron InGaAsN/GaAs vertical cavity surface emitting lasers (VCSELs). The InGaAsN VCSELs are dry etched to form a 42 micron mesa that is subsequently wet oxidized to form apertures ranging from 6.0 to 8.5 microns. The quasi-single mode laser was modulated with a pseudorandom bit s......

Experimental analysis of cross gain modulation and cross phase modulation in SOA with assist light injection
- Trang TuK1-TuK1
A simple analysis technique of cross gain modulation and cross phase modulation in SOA using delayed interferometer configuration was proposed. Recovery time and the amounts of XGM and XPM were measured in assist light injected SOA.

16-channel VCSEL based multiple chip modules
- Trang MH4-MH4
Summary form only given. We designed and fabricated the hybrid integrated CMOS-VCSEL multiple chip modules. The VCSEL operate at 850nm wavelength. A typical VCSEL has a threshold current of 4 mA, and quantum efficiency of 0.3 mW/mA. Operating at 8 mA modulation current, the VCSEL 3-dB modulation bandwidth was measured more than 5 GHz.

Design approaches and results for high speed single mode long wavelength VCSELs
- Trang WC1
Summary form only given. Optical communication links between 100 meters and 10 kilometers will require new cost effective transceiver solutions. We have demonstrated single mode and high-speed modulation in long wavelength VCSELs with low threshold current. Research is ongoing to improve high temperature characteristics and high-speed performance optimization. Coupled with component and packaging ......

Fast and efficient WDM network protection using p-cycles
- Trang WA1-WA1
p-Cycles are preconfigured protection cycles for meshed networks. A p-cycle protects on-cycle links, and off-cycle links having p-cycle nodes as endpoints. For WDM-networks, p-cycles can provide fast protection switching times and achieve high resource efficiency.
