Latest Patents

One of his latest patents is titled "Fiber assembly for all-fiber delivery of high energy femtosecond pulses." This invention relates to a fiber assembly used in chirped pulse amplification systems, aimed at improving dispersion management when utilizing hollow core photonic bandgap fibers for pulse compression. The assembly includes an optical laser oscillator, a first fiber section for stretching pulses, and a second fiber section for compressing the stretched pulses, achieving pulse compression at less than 200 femtoseconds.

Another significant patent is for a "Method for the manufacture of optical fibers and improved optical fibers." This invention introduces a universal channel dispersion compensating fiber (CDCF) designed for WDM channel compensation. It provides essentially zero dispersion slope over a wide wavelength band, allowing for the compensation of numerous channels using a single fiber design. The improved optical fiber exhibits a dispersion slope at 1550 nm of less than 0.02 ps/nm²-km, with a maximum variation of dispersion per kilometer over the S-, C-, and L- bands of less than 2.0 ps.
