Latest Patents

One of Lin's latest patents is for a compact tunable optical time delay. This device consists of an optical subassembly that applies a dispersion-free time delay to the input optical signal. It also features a mechanical subassembly that facilitates tuning the delay using a linear actuator. The design incorporates a precision optical ferrule sliding in a precision split sleeve, which minimizes optical misalignment during the tuning process. This innovation allows for a self-contained and cost-effective solution while maintaining a compact form factor. The device's exterior dimensions remain unchanged during operation, despite the internal movements. Additionally, both reflection-type and transmission-type optical time delays are introduced, which can be driven either manually or electrically.

Another significant patent by Lin is an optical isolator device designed to minimize polarization mode dispersion. This device includes a first polarization splitter/combiner, a non-reciprocal polarization rotator, and a second polarization splitter/combiner. It allows only forward propagation of light while blocking backward optical signals through non-reciprocal polarization rotation. The optical paths of the ordinary ray and extraordinary ray are arranged to achieve equal optical path lengths, effectively minimizing polarization mode dispersion. When symmetrically configured, both polarization mode dispersion and polarization dependent loss become zero in principle.
