IMPEDANCE MATCHED OPTOELECTRONIC COMPONENTS USING LOSSLESS ELEMENTS

摘要

Impedance matching using lossless elements for optoelectronic components. In one embodiment, a fiber optic link has a laser diode (10) optically coupled by an optical fiber (14) to a photodiode (12). The laser diode is matched to the RF source (16) by a reactive matching circuit (M1). The photodiode is matched to the load (18) by a second reactive matching circuit (M2). Both matching circuits are comprised of lossless elements, as opposed to resistive elements, for achieving a match with minimal RF-to-RF insertion loss.
