摘要:
Described herein is an optical transmitter that includes an RF signal path that is, at least partially, parallel with an optical signal path. In one embodiment, an electrical transmission element, which defines the RF signal path, is disposed between a laser emitting the optical signal and a side wall of a package containing the optical transmitter. Although the RF and optical signals may propagate along different planes within the optical transmitter, both signals are received at an optical modulator. Using the RF signal, the optical modulator modulates the optical signal (e.g., a continuous wave) to generate a modulated optical signal. The optical modulator then outputs the modulated signal to a receptacle coupled to a light carrying medium such as a fiber optic cable.

A device (340) for linearizing non-linear signal transmission characteristics of an optical communication system (300) is provided. A non-linearity introducing part (330) is between an input port (310) and an output port (320) of the optical communication system (300). The non-linearity introducing part (330) at least partly causes said non-linear signal transmission characteristics. The device (340) is configured for connection between said input port (310) and the non-linearity introducing part (330), in parallel with the non- linearity introducing part (330), and comprises a pair of Junction Field Effect Transistors (T1, T2), "JFETs", configured to operate in an anti-parallel configuration.
