Title: Daigao Chen: Innovator in Optical Technology

Introduction

Daigao Chen is a prominent inventor based in Hubei, China. He has made significant contributions to the field of optical technology, holding a total of four patents. His work focuses on advancements in polarization converters and photoelectric detection apparatuses.

Latest Patents

One of his latest patents is a polarization converter based on taking a high-order TE mode as a transition mode. This innovative device comprises a ridge waveguide and a slab waveguide arranged in double layers, varying in width. The ridge waveguide is positioned on the upper end face of the slab waveguide, aligning with both ends of the slab waveguide. A TM mode enters from the left ends of the ridge and slab waveguides, converting into a TE mode for output. Conversely, the TE mode enters from the right end of the strip waveguide and is converted into the TM mode for output.

Another notable patent is a silicon-germanium photoelectric detection apparatus based on an on-chip mode converter. This apparatus includes an insulating substrate, an optical coupler, an on-chip mode converter, and a multi-mode silicon-germanium photoelectric detector. The optical coupler, converter, and photoelectric detector are sequentially connected and fixed on silicon wafers of the insulating substrate. An incident fundamental mode optical signal is transmitted to the optical coupler through a single-mode fiber, entering the converter via the optical coupling. The converter transforms the fundamental mode optical signal into a multi-mode optical field, which is then converted into an electrical signal by the photoelectric detector.
