Modeling and Simulation of Photonic Crystal Cavity Quantum Dot LASER for Biosensing Application

In this paper, a detailed simulation, modeling and analysis of photonic crystal cavity quantum dot laser is discussed. A photonic crystal structure is Nano device can be implemented as a biosensor. A waveguide coupled H1 cavity based photonic crystal is represented in which, these are separated structurally by orthogonal dipole mode coupling. Construction of cavity is achieved by piercing a slab Ta₂O₂ (Refractive Index 2.0995) with air holes to form hexagonal lattice. The photonic crystal cavity quantum dot laser has two modes at 1430nm and 1491nm. Here a quantum dot is placed at a middle of the Nano photonic crystal cavity. Population inversion is achieved in a very short time because of the maximum field amplitude of le7V/m.
