Abstract: A phase retarder and an optical comb filter are disclosed. The phase retarder includes a polarization beam splitter, a first air arm, and a second air arm, where the polarization beam splitter is configured to decompose a beam into a first light component propagated in a first direction and a second light component propagated in a second direction, the first direction is perpendicular to the second direction; the first air arm is disposed on a second side wall of the polarization beam splitter, and is configured to receive the first light component and reflect it back; and the second air arm is disposed on a third side wall of the polarization beam splitter, and is configured to receive the second light component and reflect it back. Two light components interfere, and the interference light is emitted from a fourth side wall of the polarization beam splitter.

Abstract: A 3D-MEMS optical switch is disclosed. In an embodiment, the 3D-MEMS optical switch includes a collimator array, a PD array, a wedge prism, a light-splitting triangular prism, a micro-electro-mechanical system MEMS micro-mirror, and a core optical switch controller that is connected to the PD array and the MEMS micro-mirror. In the present invention, the PD array is integrated into a core optical switch, which simplifies an architecture of the optical switch and reduces a volume of the optical switch; the wedge prism and the light-splitting triangular prism are used to perform light splitting, and some optical signals are transmitted to the PD array to detect optical power, so that the core optical switch controller adjusts the MEMS micro-mirror according to the optical power, which is detected by the PD array, of the optical signal, making an insertion loss of the 3D-MEMS optical switch meet a preset attenuation range.

Abstract: A 3D-MEMS optical switch, comprising: a collimator array, a PD array, a window glass which covers the PD array and is coated with a partial reflection film, a micro-electro mechanical system (MEMS) micro-mirror, and a core optical switch controller connected to the PD array and the MEMS micro-mirror. The PD array is integrated inside the core optical switch, so that the architecture and the volume of the optical switch are simplified. The window glass which covers the PD array and is coated with a partial reflection film is used to fold an optical path, and some optical signals are transmitted onto the PD array, so that the core optical switch controller adjusts the MEMS micro-mirror according to the optical power of the optical signals detected by the PD array, so as to enable the insertion loss of the 3D-MEMS optical switch to meet a preset attenuation range.
