Message from the President

Since its establishment in 2002, Photonic Lattice has consistently delivered unique optical elements, made of “photonic crystals”, to various customers such as system manufacturers and research institutes. We continuously develop novel technology in order to keep providing valuable “photonic crystal” products, as our way to contribute to society.

Co-Creation (Founders Message)

Photonic Lattice, Inc. was founded to develop new photonic crystal products with the goal of expanding the functionalities of optical systems in a broad number of industries. Our core strength is in our process technology which enables formation of arbitrarily shaped micro-polarizers and micro-waveplates onto inorganic substrates. It is our desire to deliver integrated optical devices which can be used to advance the performance of current optical systems.

The first significant commercialization program of Photonic Lattices was the development and manufacturing of 2D measurement equipment systems. The “eye” of such systems consists of a patterned photonic crystal, a device innovated by Photonic Lattice. As Photonic Lattice wishes to make our core photonic crystal technology available to more industries, we have recently started a new business line: design and fabrication of special-purpose photonic crystal chips. A few industries which already benefit from such innovative chips include optical communications (polarization multiplexing), semiconductor wafer inspection (DUV inspection systems), and laser machining. Our photonic crystal products play essential roles in each of these fields and allow our customers, who are top-tier technology companies, to differentiate their product lines from competition.

In different branches of optics, our customers have ambitions to create new functions in their product offerings. It is our goal to help our customers to achieve their goals by mutually engaging with them in product design and fabrication. To add a few words about our technology, our products are formed by sputtering techniques which are inherently rugged and reliable. By selecting appropriate materials, we can provide products which extend from the DUV through the infrared spectra. Our materials have been confirmed to withstand high power laser light and therefore can be safely used in demanding environments. It is our hope that we can continue to expand our technologies into new application areas and build mutually beneficial relationships with our customers.

Founder, Shojiro KAWAKAMI

Management philosophy
