A multigigabit/second wavelength-division-multiplexing byte-by-byte switch using fast tunable heterodyne receivers

Fast-frequency laser tuning and a 2*2 electrooptic switch have been combined to perform byte-by-byte switching at synchronous optical network (SONET) rates using a wavelength-division-multipling (WDM) architecture. The three-section distributed-Bragg-reflector (DBR) lasers used can be tuned over a 1...

Zusammenfassung:Fast-frequency laser tuning and a 2*2 electrooptic switch have been combined to perform byte-by-byte switching at synchronous optical network (SONET) rates using a wavelength-division-multipling (WDM) architecture. The three-section distributed-Bragg-reflector (DBR) lasers used can be tuned over a 100-GHz range in 5 ns.< >
