The fine structure of the dynamically broadened spectral line of a single-longitudinal-mode InGaAsP laser under large-signal direct intensity modulation at 10 GHz was studied. It is shown that the frequency-chirped spectral line has a characteristic FM modulation spectrum with many sidebands at 10-GHz intervals and with an asymmetry due to the superposition of the a.m. modulation.

    Room-temperature continuous-wave oscillation with an emission power in excess of 1 mW was achieved in vertical-cavity surface-emitting lasers containing a 0.5-μm-thick GaAs active layer sandwiched between a distributed Bragg reflector (DBR) and a hybrid metal DBR. The devices have a cw...
