Photonic Crystal Polarizing Optical Components

Ultra-thin waveplate for optical communications

It has insertion loss comparable to that of a quartz plate and can have multiple axial orientations on a single element.
Compact and free polarization control can be realized in optical transceivers, optical modulators, receivers, and wavelength selective switches (WSS) in digital coherent systems.

True Zero Order Waveplate/Ultra-Violet Polarizers

Photonic crystal waveplates are reliable and perfect zero-order waveplates with small incident angle dependence.For example, a zero-order half-wave plate made of quartz for a wavelength of 266 nm in the ultraviolet region would be about 11 μm thick, but a photonic crystal is deposited on a quartz plate, making it easy to handle.

Axial polarization conversion element SWP Series

A waveplate with 12 axial-azimuth regions that can realize axis-oriented polarization simply by inserting it into the optical path. It converts linear polarization into radial (radial) or concentric (azimuthal) polarization. The high transmittance achieves a conversion efficiency of almost 100%. It is effective in optical tweezers, laser processing, etc.

Custom Polarizer & Phase Plates

Our products can be customized not only for the optical properties, but also for the shape and the spatial distribution of those properties. In particular, they can be made non-uniformly, having a segmented structure or a curved axis along the surface. Customization of the patterned polarizer/waveplate is welcome.
