Title: Innovations by Rena Y Yee: Pioneering Optical Technologies in Ridgecrest, CA

Introduction

Rena Y Yee is a distinguished inventor based in Ridgecrest, California, recognized for her contributions to the field of optical technologies. With a total of three patents to her name, she has made significant strides in the development of multi-layer non-linear optical polymer thin films and optical waveguide subsystems.

Latest Patents

One of her latest inventions is a process for mass producing uniform multi-layer non-linear optical polymer thin polar films. This innovative process allows for automation in the production of second-order nonlinear optical polymer (NLOP) thin films. The method involves forming a polycation layer containing an NLO-active cationic polymer with non-centrosymmetric chromophores on a substrate, followed by the formation of a polyanion layer, which also contains non-centrosymmetric chromophores. The alternating layers can be arranged upon the surface with one or more buffer layers, resulting in an ultra-smooth surface comparable to that of the substrate.

Additionally, Rena has patented low birefringent polyimides for optical waveguides. This patent describes an optical waveguide subsystem that includes at least one cladding in contact with a core. Notably, the cladding has a refractive index lower than that of the core, with either component containing a crosslinked polyimide that is predominantly meta-linked. This innovative design ensures that the polyimide presents an absolute birefringence ranging from about 0.01 to zero.
