We present R-SOAs with improved modulation bandwidth of /spl sim/1.35 GHz as WDM sources in 1.25 Gbit/s WDM-PONs. In back-to-back transmission using the R-SOA seeded by 0.6 nm-wide ASE of -20 dBm, receiver sensitivity at a 10/sup -9 /BER was - 25.3 dBm.

We demonstrate a gain-clamped semiconductor optical amplifier (GC-SOA) which has gratings under both end regions of an active waveguide. Two gratings of the new GC-SOA are fabricated in different lengths. Their lasing modes and gain characteristics are measured and analyzed with different combinations of grating lengths. It shows different gain and noise characteristics according to the measurement direction in asymmetric grating combinations.

We developed polarization-independent high-power superluminescent diodes (SLDs) for wavelength division multiplexed-passive optical network (WDM-PON) applications. The SLD presents CW output power of 150 mW, spectral bandwidth of 40 nm, polarization-dependent power variation of less than 1 dB, and spectral ripple of 3 dB at current of 1.47 A and temperature of 25 degC

A WDM-PON with 50-GHz channel spacing employing RSOA-based spectrum sliced sources is presented. Colorless operations over 32 DWDM channels are demonstrated from -10 to 80 °C in 155-Mb/s transmissions over 10 km.

We present a low-cost WDM-PON employing colorless uncooled RSOA-based spectrum sliced sources. Colorless operations over 32 WDM channels are demonstrated from 0 to 60 oC in 155-Mb/s transmissions over 25 km.
