Jennings, A. ‘Asymmetric Fabry-Perot device arrays with low insertion loss and high uniformity’ in IEEE Photonics Technology Letters, 4, 1992, pp 858 - 860
IEEE Photonics Technology Letters 4
We report on arrays of normally ON asymmetric
Fabry-Perot modulator (AFPM) devices which exhibit a high
degree of uniformity between devices, with a thickness variation
across an array of 0.07%. The devices in one array have a mean
insertion loss of 1.8 dB, and OFF reflectivities of less than 3%,
giving a mean contrast ratio of 22:l. These characteristics are
measured at a single operating wavelength of 857 nm. The
spatial light modulators show promise for the use of AFPM
devices in optical processing
