In this paper, we will describe the performance of two long wavelength 1024 × 1024 corrugated quantum well infrared photodetector focal plane arrays (C-QWIP FPAs) with cutoff wavelengths at 8.6 and 9.0 μm, respectively. The FPAs are background limi

Corrugated quantum-well infrared photodetectors (C-QWIPs) offer simple detector architectures for large-format infrared focal plane arrays (FPAs). The detector relies on inclined sidewalls to couple normal incident light into the absorbing material.

We have successfully designed and fabricated GaN-based light-emitting diodes (LEDs) containing an omnidirectional one-dimensional photonic crystal (1D PC). The 1D PC is composed of alternatively stacked TiO2 and SiO2 layers designed to possess a phot

Rigorous electromagnetic modeling based on a modal solution of the pertinent boundary-value problem was performed to study the light coupling mechanism in quantum grid infrared photodetectors with lamellar patterns. Our theory shows that vertical fie

The photonic band structure of 2D photonic crystals consisting of cylindrical dielectric rods on a square and on a triangular lattice is computed by a method which is commonly used in studying low-energy electron diffraction in conventional crystals.

We present a catastrophe-based graphic model for understanding the optical bistability (OB) of an aqueous aerosol particle detected in light scattering. The model is shown to be in good agreement with hidden resonance experiments and indicates that O
