AbstractReducing the complexity of opticalsystems emphasizes the need to increase the number of optical functions in as few modules as possible, making the system more compact and simple to operate. Optical functions such as light generation, frequency conversion, amplification, broadband transmission, wavelength filtering and interfacing to the outside environment typically needed separate, individual optical components to be chained together to comprise a system. However, with the advent of Photonic Crystal Fiber, many of these functions can be combined into multifunctional modules paving the way for simpler, turn‐key systems.
