Partow waveguide technology is based on thin films of lithium niobate that are bonded and transferred to a silicon or quartz substrate. A rib layer is directly etched on top of the electro-optic thin film layer to form the optical waveguide. The high index contrast waveguide has sub-micron mode size which requires grating couplers for coupling to the device. This high index contrast platform allows us to make advanced photonic components such as compact Mach-Zehnder modulators, micro-ring modulators and nonlinear optical devices. Partow is developing these devices.

 

We provide lithium niobate device processing. Here are the processes available:

• TFLN waveguide fabrication with loss <1dB/cm at 1550nm
• TFLN poling with periods as small as a few microns
• TFLN device passivation and electrode deposition
• Au electro-plating for high-speed transmission line
• A library of devices including grating couplers, micro-ring resonators, MMI couplers and Mach-Zehnder modulators is available upon request.
• For other wavelengths, the design of waveguides, grating couplers, etc. is available upon request
