Embodiment Construction

[0031] Figure 4 A coaxial optical layout of a high dynamic range integration (HDRI) receiver using a reflective variable optical attenuator (VOA) actuator 411 according to a first embodiment of the invention is illustrated. A divergent light beam 402 emitted from an input fiber 401 defined as an input port propagates through a silica module 403, which is placed in optical contact with the end face of the input fiber 401, and then enters the monolith through an input port defined by a first input flat surface 405 The optical device 404 , the first input planar surface 405 is also in optical contact with the silicon dioxide module 403 . The silica module 403 has a refractive index between that of the input fiber 401 and optics 404 to provide a gradual transition to minimize back reflections at its interface. Monolithic optics 404 integrates five optical interfaces including, in order of beam propagation: input planar surface 405 , collimating lens surface 406 , planar refracti...

Abstract

A high dynamic range integrated (HDRI) receiver includes a variable optical attenuator (VOA) for attenuating an incoming optical signal before the optical signal is directed to a photo-detector for conversion into an electrical signal. An optical block receives the optical signal from an optical fiber and includes optics for directing the optical signal to the VOA, and for directing the optical signal from the VOA to the photo-detector.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application No. 60 / 714,654, filed September 7, 2005, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an optical receiver with an extended dynamic range, and more particularly, to an optical receiver with an integrated optical attenuation function to achieve an extended dynamic range of operation. Background technique [0004] With the development of optical communication systems, there is an increasing demand for low-cost, high-performance optical components with extended adaptability in operation. Component integration is a key technology to provide low cost and reduced size compared to discrete component based solutions. [0005] At low optical input power, the dynamic range of the optical receiver is limited by coupling loss and photodetector sensitivity. At high optical input power, the dynam...
