12864 LCD ST7920 Interface
Interfacing an LCD12864 (ST7920 controller) to a microcontroller I am currently planning a new all band transceiver that might be a little larger than the "Microtransceivers" I built this year.

Liquid Crystal Type Optical Spatial Modulator
(MIIPS) is a technique based on the computer-controlled phase scan of a linear-array spatial light modulator. Through the phase scan to an ultrashort pulse, MIIPS can not only characterize but also manipulate the ultrashort pulse to get the needed pulse shape at target spot (such as for optimized peak power, and other specific pulse shapes). Liquid crystal modulators are a type of optical modulator which utilize liquid crystals to control the intensity, phase, or polarization of light. Liquid crystals are birefringent, so applying a voltage to the cell changes the effective refractive index seen by the incident wave, and thus the phase retardation of the reflected wave.

Iron-based liquid crystal spatial light modulator
We present the design and characterization of a spatial light modulator (SLM) comprising a ferroelectric-liquid-crystal light-modulating layer on top of a silicon integrated circuit. Spatial light modulators, as dynamic flat-panel optical devices, have witnessed rapid development over the past two decades, concomitant with the advancements in micro- and opto-electronic integration technology. However, to extend the electro-optic application of LCs into MWIR and LWIR, several key technical challenges have to be overcome: (1) low absorption loss, (2) high birefr ngence, (3) low operation voltage, and (4) fast response time. In a new review published in Opto-Electronic Science, the authors showcase the recent advances in replacing the traditional static optical toolkit with a modern digital toolkit for "light on demand.

Liquid Crystal Optical Modulator Driver Circuit
A high-efficiency low-power chip-based liquid crystal (LC) driver has been successfully designed and implemented for adaptive electro-optic eyewear including tunable vision correction devices (eyeglass, contact lens, intraocular lens, occluder, and prism), phoropter, iris .

LCOS (Liquid Crystal on Silicon) is a reflective microdisplay technology based on a single crystal silicon pixel controller backplane which drives a liquid crystal layer. Optical communications use an optical modulator to impose an (electrical) signal on continuous-wave (CW) light to vary the power and phase of the light and create an optical signal. Our solutions support symbol rates from 32 Gbaud to 128 Gbaud, enabling optical network capacities from 100 Gb/s to 1.
