Optical insertion loss

In telecommunications, insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB). If the power transmitted to the load before insertion is PT and the power received by the load after insertion is PR, then the insertion loss in decibels is given by, WebMany of the key performance metrics of an electro-optic modulator can be extracted from the modulation response, including VπLπ, the insertion loss, and the extinction ratio. In this document, we will describe the procedure for determining the modulation response using the effective index of the waveguide.
