A new dynamic model is developed for simulating the widely tunable grating assisted codirectional coupler with rear sampled grating reflector (GCSR) lasers.
For general exploringobjects requirement, narrow pulse signal with tens millimicro second to millimicrosecond has the frequency spectrum from DC to thousands MHz.
Meanwhile, experiment data and results are provided.Comparison with other methods indicates this circuit is an easy and useful noncorrelation detection method,and can get good ...
Secondly, the structures of various multicouplers and their matching networks are introduced and discussed, and the design period of broadband matching network in multicoupler is presented in brief.
