Acousto-Optic Bandpass Filters

Acousto-Optic Bandpass Filters

US PATENT # 6,647,159 Tension-Tuned Acousto-Optic Bandpass Filter
US PATENT # 6,580,841 Chirped Fiber Acousto-Optic Bandpass Filter
US PATENT # 6,556,729 Acousto-Optic Bandpass Filter


This group of patented acousto-optic bandpass filters provide three varying methods of enabling one or more wavelength bands to be selected for further transmission. Signal switching is an important function in telecommunications. With the move to fiber optic cable transmissions, the demand for lower costs and higher switching speeds steadily increased, resulting in an increased need for optical switching. These technologies perform the function of bandpass filters at a lower cost, with lower power consumption, lower optical insertion loss, more versatility, and greater reliability than other bandpass filter technologies.
