Composite resonator vertical-cavity laser diode
An electrically injected coupled-resonator vertical-cavity laser (CRVCL) diode is described. The CRVCL consists of a lower 1-λ-thick active resonator containing three InGaAs quantum wells and a passive upper resonator composed of 1-λ-thick GaAs. Some of the characteristics arising from the cavity coupling, including methods for external modulation of the laser are demonstrated.
