Wang Yuangan, Yu Honglin, Zhu Chuanxin. Design and analysis of 1×3 optical switch with grating light valve[J]. 2008,(4):48-51. DOI: 10.13756/j.gtxyj.2008.04.006.
On the basis of short response time of grating light valve and high diffraction efficiency of reflection grating
a 1×3 micro optical switch using grating light valve is designed.Theoretical calculations and experimental results indicate that when the optical wavelength is 1.3 μm and the blaze angle and incident angle are 5.4 ° and 0 ° respectively
the switching time is on the level of microsecond.Compared with other similar optical switches
it has the advantages of short switching time
high diffraction efficiency and low operating voltage.
