摘要： A right angle waveguide having a square rod-type square lattice photonic crystal and a single compensation scattering rod having a high refractive index. The right angle waveguide is a photonic crystal formed from first dielectric rods having a high refractive index arranged in a background dielectric having a low refractive index according to a square lattice. In the photonic crystal, one row and one column of the first dielectric rods having the high refractive index are removed to form the right angle waveguide. A second dielectric rod having a high refractive index is arranged at a corner of the right angle vvaveguide, the second dielectric rod being the compensation scattering rod. The first dielectric rods are square rods having the high refractive index. The right angle waveguide has extremely low reflectance and a very high transmission rate, and facilitates large-scale optical path integration.

摘要： Taught is a high sensitivity THz detector and camera comprising an integration body of a photonic crystal THz micro-cavity and semiconductor transistor on a semiconductor base. The THz signal is localized inside of the photonic crystal micro-cavity so as to generate high intensity field in the micro-cavity. The heat effect of the THz wave therein produces electron-hole pairs in the semiconductor. The current carrier is injected into the base electrode of the transistor and is amplified therein to produce signal current in the external circuit and thus high sensitive THz signal detection is realized. Integrating many such detectors together to construct a THz resonant cavity array, each resonant cavity only receives THz light from a certain position and having certain intensity. The signal is converted and then stored to obtain a complete THz image so as to realize imaging in real-time. Special signal amplification circuit is used to eliminate THz background radiation noise.
