Latest Patents

One of his latest inventions is a polarization independent all-optical demultiplexer. This innovative device generates a constant four-wave-mixing beam without being affected by the input polarization state. It utilizes a dispersion-shifted fiber, which is a nonlinear material with a high refractive index. By replacing several components in conventional demultiplexer implementations that are sensitive to input polarization with optical fibers of high polarization mode dispersion, Ahn has enhanced the functionality of optical demultiplexing.

Another notable patent is the dual cavity laser. This laser features a positively mode-locked structure that effectively doubles the repetition rate of output light. The design includes an amplitude modulator that generates two modulating signals with opposite phases simultaneously. The dual cavity laser is a modified version of the conventional single cavity laser, incorporating two resonators to achieve a repetition rate that is twice that of its predecessor. One of the resonators is adjusted to obtain two types of output optical pulses with distinct optical properties.
