Patent number: 11906780Abstract: An asymmetric adiabatic polarization beam splitter integrated with a waveband filtering splitter unit and a polarization filtering splitter unit is capable of being packaged to form an integrated optical waveguide filtering chip. The waveband filtering splitter unit utilizes an adiabatic optical waveguide structure and stimulated Raman adiabatic passage on an optical waveguide to split the energy of light sources of different bands to different spaces when the light energy is performed with an adiabatic process. The polarization filtering splitter unit utilizes the two orthogonal polarization modes of an optical waveguide with birefringence to achieve a polarization-dependent mode splitting effect based on an adiabatic theory. The asymmetric adiabatic polarization beam splitter realizes the characteristics of integration and high process tolerance, and improves the mass production feasibility.Type: GrantFiled: October 26, 2021Date of Patent: February 20, 2024Assignee: National Central UniversityInventors: Hung-Pin Chung, Kuang-Hsu Huang, Tsung-Yeh Ho, I-Ting Chung, Yen-Hung Chen

Publication number: 20230408258Abstract: A feedback module is formed with modules comprising a schedule hardware register module and a computation circuit module. The schedule hardware register module receives a modulation signal and a sensing signal, and schedules and temporarily stores signal values of the sensing signal in successive half modulation cycles in sequence by taking a half modulation cycle as a time interval to obtain a temporarily stored sensing signal which has been scheduled. In each half modulation cycle, the computation circuit module calculates a differential signal value of the temporarily stored sensing signal between the previous two half modulation cycles, and outputs the differential signal value as a signal value of the feedback signal. The schedule hardware register module temporarily stores the feedback signal, and the feedback module feedbacks the feedback signal to an integrated optics chip of the photoelectric sensing system integrated optics chip.Type: ApplicationFiled: August 9, 2022Publication date: December 21, 2023Inventors: HUNG-PIN CHUNG, BOR-WEN SHIAU, SHENG-HAN CHANG, CHII-CHANG CHEN, YEN-HUNG CHEN, JANN-YENQ LIU
