Latest Patents

One of Teng's latest patents is titled "On-chip spectroscopic sensors with optical fringe suppression." This invention features an on-chip spectroscopic sensor that includes a tunable diode laser, a laser driver, and an analyte test cavity. The device is designed to expose a chemical sample to light from the tunable diode laser, allowing an optical detector to detect the light emerging from the test cavity. A spectral analyzer then determines the spectrum of the light, removes known optical fringe patterns, and assesses the composition or concentration of the chemical sample.

Another significant patent is "Tunable diode laser absorption spectroscopy with corrected laser ramping nonlinearities." This device also utilizes a tunable diode laser and includes a laser driver configured to ramp the laser within a specific frequency range. It features an analyte gas container, a reference gas container, and a fringe generating device. The optical detector captures the laser output after it passes through the analyte and reference gas containers. The spectral analyzer processes the data to decouple the fringe spectrum and calibrate the results, ultimately determining the composition of the analyte.
