摘要：The information carrying capacity of Electronics circuits is of the order of GHz whereas the opticalwaveguides on integrated circuits can carry the information using light (Optoelectronic) i.e. using a frequency of theorder of THz. Thus optical waveguides can be used to carry the information in VLSI circuit e.g. Microprocessors at thespeed of light. The optical waveguide empowers not only an enormous bandwidth increase i.e. in the range of multipleterabits per second, but causes a decrease in power consumption, reduced immunity to temperature variations,immunity to electromagnetic noise interference, etc. Hence the design and investigation of high transmission and lowbending loss by photonic crystal waveguide has been a subject of strong interest in the past decade. In this paperdifferent technique used for designing optical waveguide bends, the different bending angles along with theirtransmission efficiency through the bend at various frequencies have been discussed and compared. From the tabularcomparison it can be observed that the material is to be chosen with a high refractive index contrast and by adjustingthe position, size, structure and refractive index of the holes at the bend to maximize the overall transmissionefficiency.
