Recovering the frequency of incoming data sequences in optical transmission lines is important for signal processing. It has been suggested to use all-optical devices, for instance lasers diodes, for this purpose. Recently, self-pulsations have experimentally been discovered in multi-section distributed-feedback lasers. If a self-pulsating laser is exposed to an external data signal, it is expe...

This paper deals with the theory and device applications of periodic thin-film waveguides. Topics treated include mode solutions, optical fiiters, distributed feedback lasers (DFB), distzibuted B r a g reflector (DBR) lasers, grating couplers, and phase matching in nonlinear interactions.

Recovering the frequency of an incoming data stream in optical transmission lines is important for signal processing. It has been suggested to use all-optical devices, for instance lasers diodes, for this purpose. If a self-pulsating laser is exposed to an external data signal, it is expected that the frequency of the self-pulsation locks to the frequency of the data signal, and clock recovery ...
