Mutually Injection-Locked Tunable Laser Based on GS-RSOAs for L-Band Generation
Heun-Duk Ku,Soo-Yong Jung,Seung-Hoen Han,Chang-Soo Park IEEE 2012 IEEE photonics technology letters Vol.24 No.24
<P>We propose a mutually injection-locked tunable (MILT) laser for L-band generation based on arrayed waveguide grating and gain-saturated reflective semiconductor optical amplifiers. The laser generates a 3-dB bandwidth less than 0.05 nm and a high and uniform sidemode suppression ratio (SMSR >;52 dB, ΔSMSR >;3 dB) over 40 L-band wavelengths. Using an MILT laser greatly reduced the phase noise, which is measured to be -107.83 dBc/Hz at a frequency of 10-kHz offset from the center. Furthermore, the 1.25-Gb/s directly modulated transmission performance of the MILT laser shows that there is a power penalty of ~ 0.2 dB over a 20-km single mode fiber.</P>
