Latest Patents

Hoi Lut Ho holds a patent for a method of gas measurement based on the photothermal effect in hollow-core optical fiber. This invention involves filling a target gas into the core of a hollow-core optical fiber. It couples a probe light and a periodically modulated pump light into the fiber. The target gas absorbs the pump light, resulting in periodic modulation of the phase of the probe light. By demodulating this phase modulation information, the concentration of the target gas can be obtained. The method allows for ppb level gas measurement with high selectivity, making it universally suitable for detecting gases with absorption in the near-infrared spectrum.
