In-house Manufacturing Technology to Manufacture These Laser Pointer Devices

The researchers created a 24-micron wide silicon disk. Use different mechanisms to limit the laser pointer and mechanical waves. The light is confined to reflect inside the device, which causes the light to bounce off the edge of the disk and surround the outer part of a circular ring. The researchers rounded the silicon disk to form the appearance of a bull's-eye, that is, the outer ring that locates the mechanical movement, which can interact with light. The disk is supported by a central base that allows the disk to be moved. The radial ring has been used to confine light waves in other devices, but we applied this method to mechanical waves. Our optomechanical device is the first to use this radial ring for the coupling of mechanical and optical waves. The flexibility of the design of the silicon disc means that it is not just for sensing movement. For example, a disk made of laser material can produce a laser with pulses or power levels controlled by motion. The device can also be used to make very small and high-frequency optical modulators for telecommunications applications. Researchers are further improving the design of their devices and using better foundry manufacturing processes for equipment manufacturing. This reduces the amount of light lost by the disk, thereby improving overall performance. They also want to combine an integrated optical waveguide that can realize light back and forth with an optomechanical disk to form a whole device that makes the laser pointer more practical.
