Abstract

An optical, wavelet-based fractal modulation of ultra-short light pulses is used as part of a high-bandwidth communications system (Fig. 2). The preferred embodiment utilizes the scheme as part of a hybrid wireless optical and RF transmission system for broadband communications among fixed and/or mobile platforms. An ultra-short pulse laser, high power WDM-ARRAY laser or high-power incoherent light sources may be used.
