Sažetak
We report on the transverse mode and polarization characteristics of a novel 1.52 gm vertical-cavity laser that utilizes an InGaAsP strain-compensated quantum- well active layer and two AIAs/GaAs quarter-wave mirrors. The 6 and 8 l~m diameter devices exhibit room- temperature pulsed threshold currents as low as 4 mA, and a maximum output power of 14 mW was measured on a 60 gm diameter device. L ong- wavelength vertical- cavity lasers are potentially integrable low-cost sources for optical communication systems. The practi- cal choice for 1.3 lma and 1.55 gm emitting/absorbing material is the quaternary InGaAsP alloy lattice matched to InP. The difficulty in using this material system lies in the relatively small refractive index va- lues that can be achieved by varying the InGaAsP composition. A large refractive index ratio is essential for the realization of high reflection coefficients in practical distributed Bragg reflectors.
