Theoretical and Experimental Investigation of SGDBR on Sampled Grating
|
Abstract:
The impact of the sampled grating in a distributed Bragg reflector laser on the tuning range,output power,and side-mode suppression ratio(SMSR) are investigated in detail.Design criteria are proposed,and the results are applied practically.The reflection spectrum of the sampled grating in the device is consistent with our design and a 30nm quasi-continuous-wave tuning range with SMSR>30dB is achieved.
