The design of an eight-channel 25 /spl mu/s wavelength-division-multiplexed (WDM) microwave photonic delay line is described. The performance of the delay line was studied by measuring the temperature dependent relative phase drift between channels a

We present a CW LIDAR utilizing telecommunications components and operating at eye-safe wavelength of 1550 nm. Our direct detection LIDAR relies on a pseudo-noise phase coded RF sub-carrier to perform range determination. We demonstrated a range reso

This paper proposes and demonstrates a new architecture for the transmission, heterodyne reception, and correlation of direct-sequence (DS) signals encoded onto an optical carrier. The approach is practical for pseudo-noise in-modulated laser radar a

A mode-locked laser is used to synchronize jitter-free ultrawideband (UWB) pulse generation at an array of UWB antenna elements. The jitter-free pulses radiated by each element add together in free space to produce a radiated field pattern that is st

We present the first demonstration of a new receiver for digital time-hopped spread-spectrum wireless communications. The time-hopped system is based upon the transmission of short radio frequency (RF) pulses with bandwidths exceeding 200 MHz. The ne

Jitter-free photoconductive (PC) switching is employed to generate a jam-resistant, time-coherent ultra wideband (UWB) pulse train. The power from multiple PC switch triggered antenna elements is combined in free space to produce a steerable UWB beam
