Abstract
A compact photonic time delay unit. The unit includes a plurality of compact optical delay elements, a plurality of delay bypass elements, with each delay bypass element being associated with a respective one of the compact optical delay elements, and a plurality of compact optical switches. Each of the compact optical switches is configured to controllably switch an optical signal through one of the compact optical delay elements or through the associated delay bypass element. In some aspects, the compact optical delay elements, delay bypass elements, and compact optical switches are disposed on a single electro-optical chip.
