Single-chip Linear Optical Amplifier

摘要

Amplification is a key function in optical networks. Traditionally, amplifiers have been used to compensate losses in optical fiber, enabling longer communication links. Today, amplifiers are being used in increasingly diverse functions ranging from power boosting of transmitters to loss compensation in optical add-drop nodes. Common to all these applications is the requirement to meet optical performance parameters within demanding cost, size and power constraints. The single-chip linear optical amplifier (LOA) is a solution that offers advantages as a discrete module, but also enables higher levels of integration. Examples of system performance and integrated solutions, utilizing the LOA, will be shown.
