    Frequency Modulation Optical Transmitter Types

    There are various types of transmitters used in transceivers, each with specific applications and characteristics. This article delves into five key types: EML, VCSEL, DFB, FP, and MZM. EMLs combine a distributed feedback (DFB) laser and an electro-absorption modulator (EAM) in a. Optical modulators are devices that modify the properties of light, such as its amplitude, phase, frequency, or polarization, in response to an external signal. These devices play a crucial role in modern optics and photonics, enabling the manipulation of light for various applications. Depending on which property of light is controlled, modulators are called intensity modulators, phase modulators, spatial light modulators, etc. A modulation scheme continuously alters the property or properties of a waveform. In this case, it is light, in order to encode the binary information.
