Study on Optical Characteristics of InGaAsP/GaAs SQW Lasers
Al-free InGaAsP/GaAs single quantum well separate confinement heterostructures have been grown by liquid phase epitaxy (LPE). The measurements showed that the far-field distribution was approximately a Gaussian profile. The refractive index profile of dielectric optical waveguides was analyzed by theory of grading waveguide. The work is useful for improving the beam quality.
