چکیده
In this work, the spectral properties of distributed Bragg reflector-based photonic crystal (DBR-PhC) structures were studied for near-infrared (NIR) range. Different structural varied to study their effect on quality stopband and appearance resonant dips in reflection spectra DBR-PhC structure. The investigated features included depth PhC holes, hole radius, number elements DBR 11-layered structure was designed with a 2.4/1.4 refractive index contrast alternating layers. aimed achieve optical filtering structure, simplify complexity Fabry-Pérot filters by eliminating FP cavity upper-DBR mirror. proposed device can be used different sensing applications.
