Chapter 3 Direct And External Modulation

Principle of Direct Modulation Optical Transmitter

The basic principle of DML modulation technology is to directly control the current through the laser to emit light of different intensities. The core function of an optical transceiver is to achieve optical-electrical conversion. Below is a simplified working principle diagram: Figure 3 Working Principle Diagram of Optical Transceiver The optical signal transmitted through optical fibers is not constant; instead, it is a modulated. In the introduction of product parameters of optical modules, we often mention the modulation mode as a key indicator, DML (Directly Modulation Laser) and EML (External Modulation Laser) are two major modulation technologies for optical modules. Direct and external modulation are primarily used in the optical domain with LED and Laser devices as methods for converting electrical data into optical. Four types of sources are commonly used, LEDs, fabry-perot (FP) lasers, distributed feedback (DFB) lasers and vertical cavity surface-emitting lasers (VCSELs). All three are tiny semiconductor devices.
