Home / Basic parameters of active optical devices
This chapter describes the key optical components used in a contemporary optical communication system; basic signal and noise parameters; major channel impairments, including chromatic dispersion, polarization mode dispersion (PMD), and fiber nonlinearities; and the. This area is commonly reduced to the horizontal (HFOV) (HFOV) or vertical (VFOV) (VFOV) dimension for ease of calculation. PICs bring photonics into the realm of integrated electronics by merging, in a compact design, photonic components such as lasers and modulators with opto-electronic, electro-optical, fully electronic or even RF functionalities and endless potential in applications ranging from medicine to data. Before you can get the right instrumentation and set-up, you have to be familiar with basic optical parameters and terminology of photometry (measurement of visible light) and colorimetry (measurement of colors), so you can be sure you are measuring what you really need to know.
