Title: Innovations of Christopher Chase
Introduction
Christopher Chase is an accomplished inventor based in Kensington, CA (US). He has made significant contributions to the field of optics, particularly in the development of advanced lens systems and saturable absorbers. With a total of 3 patents to his name, Chase continues to push the boundaries of optical technology.
Latest Patents
Chase's latest patents include groundbreaking work on planar, high NA, low loss transmitting or reflecting lenses using sub-wavelength high contrast grating. These planar lenses and reflectors utilize subwavelength high-contrast gratings (HCG) that feature high index of refraction grating elements. These elements are strategically spaced apart in both straight and curved segments, surrounded by low index material. The design allows the high-contrast grating to receive incident waves, exciting multiple modes within the grating for effective reflection and transmission. The innovative structure is configured to provide double focusing, exemplified in vertical cavity surface emitting laser (VCSEL) applications.
Another notable patent involves a high-contrast grating based saturable absorber for mode-locked lasers. This saturable absorber is designed with a buried layer of quantum structures for absorption, making it particularly effective in mode-locked applications. The HCG-SA offers three times the bandwidth of traditional distributed Bragg reflector (DBR) structures, while also exhibiting a lower saturation fluence due to field enhancement within the grating. The varying grating bar width contributes to lensing effects on the optical output, enhancing the overall performance of the laser systems.
