SYSTEM FOR PRODUCING OPTICAL PULSES OF A DESIRED WAVELENGTH USING CHERENKOV RADIATION

摘要

The present invention includes an apparatus and method for producing optical pulses of a desired wavelength. The apparatus includes an optical pulse source operable to generate input optical pulses at a first wavelength. The apparatus further includes a higher-order-mode (HOM) fiber module operable to receive the input optical pulses at the first wavelength, and thereafter to produce output optical pulses at the desired wavelength by exciting Cherenkov radiation using the input optical pulses. The present invention also relates to a method of producing optical pulses having a desired wavelength, where the input optical pulses have a first wavelength and a first spatial mode and the output optical pulses have a second wavelength and a second spatial mode, which may be converted to another spatial mode.
