Latest Patents
Jiawei Shi holds a patent for a Hybrid Optical Parametrically-Oscillating Emitter. This invention is an optical-resolution photoacoustic microscopy (OR-PAM) system designed for visualizing water content deep within biological tissue. The system utilizes an all-fiber 1930-nm hybrid optical parametrically-oscillating emitter. It features a tunable laser source whose output is amplified by a first erbium-doped fiber amplifier (EDFA). The output of the first amplifier is modulated with a Mach-Zehnder amplitude modulator that receives an RF signal with a nanosecond pulse width and a multiple kilohertz repetition rate. A second EDFA further amplifies the signal and passes it to a fiber circulator, which delivers it to a 1950/1550 mm fiber wavelength-division-multiplexing coupler (WDM). The coupler introduces the signal to a cavity that includes a spool of highly nonlinear fiber and a Thulium-doped fiber amplifier (TDFA). From the TDFA, the signal reaches a 50/50 fiber coupler that sends part to a second output TDFA and guides part back to the cavity through a port of the WDM.
