A light distributing device (100) comprises a thin planar waveguide (10) and a waveguiding ridge (20). An incoming light beam (B1) coupled into the ridge (20) forms a second light beam (B2) waveguided in the ridge (20). The ridge (20) and the planar waveguide (10) have a common portion (23) such that light is further coupled from the side of the ridge (20) into the planar waveguide (10) through said common portion (23). Thus, optical power of a broad incoming beam (B1) may be effectively coupled to a relatively thin planar waveguide (10). The planar waveguide (10) may further comprise diffractive out-coupling elements (30) to direct light towards a display (400).

A laser communication crosslink system employs an n^th order sigma delta modulator with a laser transmitter for communicating an analog input signal in binary form as a pulse width modulated signal, and employs a digital filter with a receiver for providing a digital output signal representing the value of the analog input signal. The pulse width modulated laser signal is communicated between the transmitter and receiver over a laser crosslink that may be fiber optic. The direct modulation using the sigma delta modulator with the transmitter and using the digital filter with the receiver reduces system complexity and power consumption.
