Paper Abstract

Vertical-cavity surface-emitting lasers (VCSELs) have wide applications in data communication, sensing, and consumer electronics, because they have many advantages, such as circular beam, low power consumption, high modulation speed, low cost, high reliability, and 2D array configuration. Metastructure like high-contrast grating (HCG) has many unique optical properties which can be used to construct novel VCSELs. Here we study the TE-polarization HCG for 940 nm wavelength range and design high-quality HCG-based vertical cavities with heterostructures aiming at HCG-VCSEL. The TE-polarization HCG-VCSEL at 940 nm is finally designed with a Q-factor of ~3.6×105.
