Abstract: An optical switch chip, an optical switch driving module, and an optical switch driving method are disclosed. The optical switch driving module includes an optical switch chip, and the optical switch chip includes multiple optical switch units. The optical switch units are divided into N groups, where N>=1. Each group of optical switch units shares a pair of electrodes, each pair of electrodes is configured to connect to a multi-frequency driving signal source, and each optical switch unit connects to the multi-frequency driving signal source by using the band-pass filter. Pass bands of M band-pass filters that are connected to M optical switch units in a same group are different, where M>=2. The multi-frequency driving signal source outputs multiple driving signals of different frequencies that are respectively corresponding to the M band-pass filters, so as to drive the optical switch unit.

Abstract: A cross waveguide includes a first waveguide and a second waveguide, where the first waveguide and the second waveguide are mutually perpendicular and crosswise disposed, an area formed by a cross part of the first waveguide and the second waveguide is a cross area, the first waveguide and the second waveguide each include a shallow etching part and a core layer, and the shallow etching part is symmetrically distributed on two sides of the core layer in a length direction relative to an axis of the core layer. By appropriately adjusting a width of the core layer or a width of the shallow etching part, an energy loss generated during optical wave transmission in the cross waveguide can be effectively reduced.
