衰减器

The device is fabricated by nonsilicon surface micro-machining, which uses the photoresist and the sputtered copper thin films as the scarificial layers, and the electroplated ferronickel as the structure layer to fabricate the optical MEMS components. The device consists of an electroplated ferronickel optical shutter interposed in a gap between two fiber alignment componets, an electroplated planar coil, a silicon spring, and two fiber alignment components with V-shaped grooves.
