“…Both the center frequency and bandwidth tuning of BPF [7] is proposed. Generally, diplexers are used to achieve the multifunctional filters with dual-operation [8,9]. A switchable BPF-LPF [10] is designed by merging two output ports of the diplexer with incorporating switches.…”

A sampled grating distributed feedback (SGDFB) laser diode integrated with a sampled grating distributed Bragg reflector (SGDBR) is designed, fabricated, and characterized. In the proposed laser diode, only two tuning currents, one into the longitudinal mode tuning electrode and the other into the SGDBR tuning electrode, are required, which provides an easier tuning mechanism. A split-step timedomain modeling is used to simulate the designed tunable laser diode and it is shown that a tuning range of about 27 nm with the side mode suppression ratio (SMSR) larger than 50 dB for the particular device. The designed SGDFB-SGDBR laser diode is fabricated using buttcoupling interface between the active and passive waveguides in an InGaAsP/InP platform. The tuning range of the fabricated device is about 20 nm with the SMSR of about 30 dB. The fiber-coupled output power is about 8mW for the tuned lasing modes. The measured results exhibit the proof-of-concept of the SGDFB-SGDBR laser diode despite the room for improvement in the design and fabrication processes.

Current IP/ATM routers use an electrical switching fabric/backplane and either optical or electrical interconnects between the line cards to route data. An electrical backplane and associated connectors limit the number of high speed interconnections due to practical considerations. Scaling these so-called third generation routers to the terabit regime with high port densities faces enormous problems due to the high interconnect and electrical power density. Packet routers with an optical switching fabric are considered as the next generation of IP/ATM Multi-Service routers which enable scalability towards the Terabit and Petabit regime. In this paper, various architectures with electrically active or passive optical switch fabrics will be highlighted and differences in terms of switching speed and scalability will be discussed. Recent results using a passive Array Waveguide Grating (AWG) router and fast wavelength tunable laser are presented in the second half of this paper.
