In this paper we design InAs/GaAs QDs photodetector based on photonic crystal (PhC) slab for mid infrared (IR) range. The active layer is located in PhC cavity with resonant mode of 2.9μm. QDs dielectric function using Lorentz dispersion is inserted to Maxwell equations and then equations solved with 3 dimensional finite difference time domain method. Results show light-matter interaction at this mode and absorption spectrum for this mode with full width at half maximum of 0.87μm, increase up to 8 times compared with other wavelengths.
Keywords: Photodetector, Photonic crystal, FDTD, Quantum Dot, Infrared.
