Introduction Optical transmission uses pulses of light to transmit information from one place to another through an optical fiber. The light is converted to electromagnetic carrier wave, which is modulated to carry information as the light propagates from one end to another. The development of optical fiber has revolutionized the telecommunications industry. Optical fiber has […]

Advanced Optical Components – Optical Filter
Optical Filter is a device that selectively permits transmission or blocks a range of wavelengths. Optical filters are typically bandpass or band-reject (shown in the figures below). A bandpass optical filter allows a certain range of optical wavelengths to pass and attenuates the rest (left), while a band-reject optical filter attenuates a band of optical […]
