Silicon Photonic Crystals Towards Optical Integration

Anomalous transport of light in photonic crystal

“…Integrated optical devices that are built in the platform of silicon 2D PC slab has been extensively investigated in the infrared wavelength because of the superior infrared optical properties of silicon and relative ease of nanofabrication and monolithic integration of various planar optical devices. These structures are usually made from perforating 2D periodic arrays of air holes on a silicon thin membrane suspended in air, so they are also called the air-bridged structure [57][58][59][60][61][62]. As the effective refractive index of the silicon membrane is much larger than the air background, infrared light can be confined within the membrane via the well-known physical mechanism of total internal reflection effect.…”

“…The transmission spectra of a PC structure effectively reflect its optical properties. To get this important physical quantity, we have set up an experimental apparatus that involves several functional components [61,62]. The PC samples are placed in the center of the stage, with its two sides connected with the input and output optical fibers.…”
