Abstract
In this paper, a vertical cavity surface emitting laser (VCSEL) is designed based on Fibonacci photonic quasicrystal (FPQC) cavity. This laser uses a light source with a spectral center of 460 nm. Two different FPQC structures are designed and optimized to serve as the total reflection mirror (TRM) and the transmission mirror (TM) of the resonant cavity, respectively. Compared with the distributed Bragg reflection (DBR) cavity, the designed FPQC cavity laser has smaller far-field divergence angle and relative mode field area, as well as higher brightness.
