Discuss Performance of Corner-Cube Prism for Modulating Retro-Reflector Terminal in Free-Space Laser Communication
Modulating Retro-reflector terminal does not need capture, tracking, targeting(ATP) sub-system .The key unit of this type structure is corner- cube prism,its performance will cause the light beam intensity distribution and light beam divergence angle .There are several factors ,such as effective area , right-angle accuracy, surface-type errors .Those errors caused loss of light power result in communication fail,so in this paper we made a precise analysis as a supplement.
On the effective reflection area of a cubic corner reflector
The effective reflection area of a cubic corner reflector is defined , it is testified for the cubic corner reflector that the ray reflect from this prism is not parallel with the ray incident on the corner of undersurface of this prism , the effective reflection area is calculated in the case of the ray incident on the undersurface of this prism vertically , the acreage of the effective reflection area is two thirds as that of the undersurface of this prism .
Strategies for glass based photonic system integration
There is a clear tendency to integrate more and more opto-electronic and micro-optical components like optical fibers, laser diodes, modulators, isolators, beam-splitting components and micro lenses in also increasingly dense and complex assemblies. The paper will discuss thin glass as a very promising base material for that kind of photonic packaging on interposer and board level including optical interconnection using fibers.
