Quantifi Photonics
Quantifi Photonics designs and manufactures a broad range of instruments that are well-suited for general-purpose photonics testing.
The typical photonics test set up comprises the following elements:
Device-Under-Test (DUT)
The DUT can be a wafer, a die, or a packaged part, with a specific optical function such as an array of ring resonators, or laser diodes, or a more complete integrated optical transceiver function.
Stimulus (light in)
A stimulus is required to activate the device, which can be a polarized light beam of a certain wavelength, or a swept wavelength laser to present the whole spectrum of interest. In some cases, an electrical stimulus may be required to activate the desired test mode.
Control
There typically is a need to control the DUT, either to just initialize it or to step through the device settings for optimization purposes. For instance in case of the broadly adopted Common Management Interface Specification (CMIS) interface a low speed I2C is chosen to accomplish this task.
Power
The device needs to be powered with the proper power supply lines to be able to operate as intended, and in addition certain bias voltages may be required for the desired operation.
Measurement (light out)
This can cover optical power levels to test waveguide quality and alignment, the optical spectrum of lasers or wavelength multiplexers and filters, all the way to high-speed signal eye diagram measurements such as TDECQ, AOP, ER, and jitter.
