The modulation properties of the composite-resonator vertical-cavity lasers (CRVCL), when one cavity is forward biased with a constant current, and the other cavity has dc plus a microwave electrical signal, were investigated. CRVCLs are composed of a monolithic p-type distributed Bragg reflector (DBR) with 35 periods, a middle n-type DBR with 14.5 periods, and a top p-type DBR with 21 periods. CRVCLs have the unique ability to lase on both a short and long wavelength longitudinal mode. Small-signal modulation bandwidths of nearly 10 GHz for a CRVCL with two separate, active optical gain regions were achieved.
