Abstract

Discovery of TCC-VCSEL done by Dr. Dalir (PI) in 2013 led to new functionalities of VCSEL structure. In principal, a TCC-VCSEL has same vertical structure as conventional VCSEL. A VCSEL is consists of two distributed Bragg reflector (DBR) mirrors parallel to the wafer surface with an active region consisting of one or more quantum wells for the laser light generation in between. The planar DBR-mirrors consist of layers with alternating high and low refractive indices. Each layer has a thickness of a quarter of the laser wavelength in the material, yielding intensity reflectivity’s above 99%. High reflectivity mirrors are required in VCSELs to balance the short axial length of the gain region. Here we assume a TCC-VCSEL with a coupling of K between the cavities. We pump one cavity with a gain of g, while the other cavity has loss of ɣ. It is noted that the lasing frequency is a function of loss and coupling between the cavities. Assuming a constant coupling (K), tunabilty of the TCC-VCSEL will be adjusted by the loss. The three-dimensional simulation of the single mode operation in TCC structure is performed by employing film mode matching method of FIMMWAVE Photon Design Corp. With a coupling of K= 1.5THz, a 19.7 nm wavelength will be swept in the PT regime crucial for lab-on-a-chip integrated bio-sensor applications.
