Two or three inches epiwafers grown by MOVPE are available for 850nm vertical cavity surface emitting laser (VCSEL) fabrication.\u00a0 The active region comprises three quantum wells of GaAs\/Al0.3<\/sub>Ga0.7<\/sub> As sandwiched by AlGaAs layers to form a resonant cavity between P- and N-DBR mirrors. Since N-DBR has higher reflection, the light is emitted from the P-DBR mirror to from the laser beam.\u00a0 We offer two types of wafers for making either ion-implanted or oxide-confined lasing aperture.<\/p>\n
