About Optical Simulation
In order to meet the various requirements of our customers, we possess several in-house optical simulation technologies.
In addition, we are constantly developing simulation technologies to realize state-of-the-art optical elements.
Here is an example.
Optical Multilayer Simulation
Simulation results of transmittance and reflectance of optical multilayers.
They are the key to the accuracy of our photonic crystal products.
Simulates the behavior of light, which is a wave.
It is essential for the design of photonic crystals.
(Beam propagation method, FDTD method)
Simulates the state of polarization.
This technique is indispensable for calibration of birefringence measurement systems and ellipsometers, and analysis of measurement results.

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
Reflectivity for each polarization can be tuned separately. As a half-mirror in a laser resonance cavity, the element is used to generate and select the output polarization of the laser. Because of its inorganic nature, the element can withstand very high optical power.
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.
Next-generation Optical Communications
Polarization control is becoming increasingly important in next-generation optical communications. In addition to application examples of our proprietary photonic crystals, we also introduce upcoming functions in the future.
Ultra-precision micro laser processing
Microfabrication technology is becoming increasingly important for next-generation EVs and semiconductor devices. We support the development of this field with our unique beam shaping, polarization control, and high speed temperature imaging technologies.
