T. Otsuji et al., 46GBIT S MULTIPLEXER AND 40GBIT/S DEMULTIPLEXER IC MODULES USING INALAS/INGAAS/INP HEMTS/, Electronics Letters, 32(7), 1996, pp. 685-686
The authors report 46Gbit/s 2:1 multiplexer and 40Gbit/s 1:2 demultipl
exer IC modules using InAlAs/InGaAs/InP HEMTs. Each chip is mounted on
a dedicated broadband chip-size cavity package. These modules are the
first to provide an error-free 40Gbit/s multiplex/demultiplex operati
on.
