Liquid crystal on silicon technology and reconfigurable all-optical networks

Abstract:Modern telecommunication networks use wavelength division multiplexing(WDM) technology to increase the transmission capacity of the fibres．Wavelength selective switches (WSSs) based on the liquid crystal on silicon (LCOS) technology enable network operators to route the signals on the wavelength basis,which significantly reduce the operational expenses(OpEx)．This paper reviews the development of LCOS-based WSSs and its role in reconfigurable all-opticaltele communication networks．The key performance parameters for the WSSs and LCOS devices are explained in great details,with an aim to promote the research and development of this field． Key words:liquid crystal on silicon; wavelength selective switch;all-optical networks;ROADM

Sub-millisecond switching of multi-level liquid crystal on silicon spatial light modulators for increased information bandwidth

Abstract: Sub-millisecond response time with a refresh rate higher than 2000 frames per second (fps) and no degradation of the contrast ratio or diffraction efficiency is demonstrated in working liquid crystal on silicon (LCOS) spatial light modulators (SLMs) with 8-bit grey levels of amplitude and phase modulations. This makes possible to achieve an information bandwidth of about 190 Gb s 1 with a 4k LCOS operating at 10-bit phase modulation levels. The normalised contrast stays at almost the unit level for a frame rate up to 1700 fps and at higher than 0.9 for 2500 fps. The diffraction efficiency stays above -1.0 dB for a frame rate up to 2400 fps. Such a fast response allows us to eliminate image blurring in replaying a fast movie.

Fundamentals of phase-only liquid crystal on silicon (LCOS) devices

This paper describes the fundamentals of phase-only liquid crystal on silicon (LCOS) technology, which have not been previously discussed in detail. This technology is widely utilized in high efficiency applications for real-time holography and diffractive optics. The paper begins with a brief introduction on the developmental trajectory of phase-only LCOS technology, followed by the correct selection of liquid crystal (LC) materials and corresponding electro-optic effects in such devices. Attention is focused on the essential requirements of the physical aspects of the LC layer as well as the indispensable parameters for the response time of the device.Furthermore, the basic functionalities embedded in the complementary metal oxide semiconductor(CMOS) silicon backplane for phase-only LCOS devices are illustrated, including two typical addressing schemes. Finally, the application of phase-only LCOS devices in real-time holography will be introduced in association with the use of cutting-edge computer-generated holograms.
