Photonic Lattice founded in Sendai, Japan in 2002. It’s core technology is photonic crystal technology, in which micro-polarizer arrays with various axis directions are freely patterned and stacked on a single wafer using sputtering technology. This technology is used as a core component in optical communications (polarization multiplexing), semiconductors (inspection using DUV light), precision processing (beam shaping), and other cutting-edge equipment in various fields.
Today, through research and development of applied technologies such as special optics and computational algorithms, we have realized unique products such as our proprietary birefringence measurement system, polarization high-speed camera, ultra high-speed and high-sensitivity thermal imaging camera, and carbon dioxide imaging system, enabling us to visualize and measure phenomena that were previously difficult.

Photonic Crystal Polarizing Optical Components
Ultra-high integration polarizers and waveplates using photonic crystals.
They feature high resistance to ultraviolet and freedom in the integration pattern layout.
01 Operating Wavelength ranging from DUV to near Infrared
Operating wavelength can be chosen in the 250nm~1600nm range, for which we provide an optimal design given our customer requirements (specs).
02 Very Precise Control of Axis Orientation
We provide very accurate control for axis orientation of polarizers and waveplates, which can be tuned finely over the surface, in areas as small as a 1μm.
03 High-Power, High Heat Resistance
The components are made of inorganic materials, making them very resistant to high-power light input. They are also heat-resistant, having almost no temperature dependence.
04 Outstanding Optical Properties
With optional Anti-Reflection (AR) coatings, the elements exhibit very small absorption & diffusion, while providing high transparency. Moreover, phase plate elements are True-Zero Order, making them ideal for applications requiring small wave front perturbation, while providing very small dependence on incident angle.
Photonic Crystal Polarizing Optical Components listed below:
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.

Half-Mirror Polarizer for Laser Cavity

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.
In addition, since the material is composed entirely of inorganic materials such as hafnium oxide, it remains unchanged even at high temperatures of 400°C and has a high degree of reliability.
The insertion loss is comparable to that of a quartz plate, and multiple axial orientations can be provided on a single element.
