An optical circulator is a three- or four-port designed such that entering any port exits from the next. This unique device has broad applications in many fields, from optical telecommunications to fiber-optic sensor systems. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but.

Depending on the parameter of a light beam which is manipulated, modulators may be categorized into amplitude modulators, phase modulators, polarization modulators, etc. These devices play a crucial role in modern optics and photonics, enabling the manipulation of light for various. External optical modulation technique is widely used due to its advantages, such as higher data transfer rates, better transmission efficiency, and performance. Although, this method increases the complexity of the system to additional modulation components.

Splitters are passive optical devices that divide or combine optical signals, and they come in various types, including power splitters, uneven splitters, and wavelength-division multiplexing (WDM) splitters. Each type serves specific applications, enabling efficient use of optical infrastructure. It redistributes incoming light signals into multiple outputs without requiring any active conversion or electrical power (3). An optical splitter is a crucial passive fiber optic device that splits and combines optical signals.
