On The Modal Performance Of Micro-cavity Semiconductor Laser With Oxidized Aperture

In this paper, micro-cavity semiconductor laser (MCSL ) with pillar vertical-cavity surface-emitting structure (VCSEL) which has potential applications in optical communication and optical interconnect is theoretically analyzed, the calculation model that used to discuss the modal performance of rectangular columnar and cylinder VCSEL with oxidized aperture is established by using Vector Field Model. The numerical simulations in the case of cylinder structure show oscillating wavelength and threshold gain against inside and outside radius of laser, the layer refractive index and pair number of Bragg mirror, thickness, position and oxidized material's refractive index of oxidized aperture, in detail. More practically, considering DOS shell of laser as non-perfect one, or supposing that DOS shell is separated from the laser, we can obtain more significative results. What we give in the work provides important instruction for the design of MCSL with optimized performance.
