Latest Patents

Pekny's latest patents include a "Line periodically poled LiNbO.sub.3 (PPLN) optical parametric oscillator." This invention relates to a three-stage PPLN optical parametric oscillator/difference-frequency generator configuration. It allows for the simultaneous generation of three wavelengths while efficiently utilizing the pump signal. The first embodiment features a first PPLN element with two grating regions and a second PPLN element with its own grating period. An input coupler is strategically positioned at both ends of the resonator cavity, with the first PPLN element placed between the input coupler and the second PPLN element. The second embodiment consists of a single PPLN element with three separate grating regions, positioned between input and output coupler mirrors. The third embodiment also includes a single PPLN element with three grating regions, with couplers affixed directly to the input and exit facets.

Another notable patent is the "Quadruple grating period PPLN optical parametric oscillator difference." This invention pertains to a four-stage PPLN optical parametric oscillator/difference-frequency generator configuration. It enables the simultaneous and colinear generation of four wavelengths while efficiently using the pump signal. The first embodiment features a singly resonant cavity containing a monolithic non-linear optical medium divided into four regions, each with its own grating period. The cavity is bounded by input and output mirrors. The second embodiment consists of a monolithic non-linear optical medium divided into four separate regions, with coatings on the entrance and exit facets acting as cavity mirrors.
