“…A bulk grating [1,2] or an arrayed-waveguide grating (AWG) [3,4] is often used as a spectrometer. While a micro-electro-mechanical system (MEMS) [1,2] mirror array or a liquid-crystal on silicon (LCOS) [3,4] is often used as an SLM. The SLM can provide a quadratic phase modulating, thus producing variable chromatic dispersion in each channel.…”

Channelized tunable optical dispersion compensators (CTODCs) based on spatial light modulators (SLMs) are considered as enabling devices for future all optical high speed dynamic networks. This paper analyzes the relationship between CTODC bandwidth and its compensation range. Analytic expressions for the coupling loss spectrum of CTODC based on liquid-crystal on silicon (LCOS) are presented. These expressions can be useful tools for the bandwidth estimation and design of CTODC based on LCOS.

“…We have many types of tunable CD compensators for the adaptive compensation. They are basically implemented by the dispersive medium with the function of tunability, for example, chirped fiber Bragg grating (CFBG) with heater elements (Matsumoto et al, 2001;Eggleton et al, 2000), micro-electro mechanical system (MEMS) (Sano et al, 2003), ring resonator (Takahashi et al, 2006), and so on. We adopt a virtually imaged phased array (VIPA) compensator in the following research.…”

In this paper, a novel spatial light modulator is presented. A pixel of the novel spatial modulator is turned fully OFF when all pixel ribbons form a flat reflective plane and turned ON by electrostatically deflecting alternate ribbons to produce a blazed diffraction grating. According to scalar diffraction theory, the optical performance is analyzed in details. And the influence factors on diffractive efficiency are discussed. Meanwhile, with the application of electromagnetics, electrodynamics analysis is introduced including the relation between threshold voltage and structure material characteristic. Computer simulation on the condition of different incidence light, different duty-cycle is carried on, presenting the relation between diffraction efficiency and wavelength, dutycycle, etc. There is a promising foreground based on optimization of structure.
