Service for Si waveguide.png
Adhesive fixation of the Si waveguide chip and fiber eliminates the need for a high-precision stage during chip characterization, making handling easier.

It can also be combined with a base plate that fixes the chip or a PCB board.

In addition to experimental samples, please use it to create samples for display and storage.

Main service contents

Fiber array connection

Adhesive fixation of the chip and fiber eliminates the need for equipment such as a high-precision stage when evaluating chip characteristics, improving the reproducibility of optical characteristics.

Optical evaluation of chips before bonding

Evaluate chip optical loss and spectrum. By performing preliminary evaluation of the chip, it is possible to select a good port and connect it to the fiber.

Combination with PCB board

By connecting the electrode pattern of the chip and the PCB board for development with wire bonding, it becomes easy to evaluate the electrical characteristics.

Si waveguide connection example

Example of mounting to a fixed frame.png
Example of mounting on a fixed frame
A fiber array is attached to both ends of the Si waveguide chip, and attached to a fixed frame to avoid stress on the connection.

It is easy to handle and convenient for evaluation of various chips (electricity, temperature, wavelength characteristics) and storage.
