Embodiment Construction

[0043] The laser source provides 107 to provide a 1310nm optical signal. These optical signals are transmitted to the common optical path 106 and output to the input / output terminal 101 through the WDMs 102 and 103 . Those skilled in the art of optical waveguide design will recognize that it is best to avoid the existence of 1310nm wavelength signal propagation within an active substrate waveguide designed to support 1550nm optical signals, which is referred to as the common optical path of the triplexer 106. Thus, a monolithic semiconductor implementation of the optical triplexer 100 partially attenuates 1310 the optical signal it generates. Thus, the 1310 nm laser source 107 provides an optical signal at a substantially higher intensity than that provided by the input / output terminal 101 . Unfortunately, this directly increases the cost of the triplexer by increasing the design of the laser employed and reducing the available power of the laser source 107. In some circums...

Abstract

An optical triplexer design is described in which external optical signals at a first wavelength range propagate through a laser source. The laser source provides optical signals having a second wavelength range. The triplexer features a photodetector for providing intensity feedback signals to the lasers source and a dense wavelength division multiplexer for demultiplexing the external optical.

Description

technical field [0001] The present invention relates to optical duplexers and triplexers. The optical component is often used in a fiber to the home (Fiber to the Home, FTTH) system. In particular, the present invention relates to the design and wiring of optical underlying components that form efficient and low cost optical duplexers and triplexers. Background technique [0002] Fiber-to-the-home systems (FTTH) support various communication devices and servers. At the same time, various architectures have been proposed and evaluated, and the prevailing method today is based on Passive Optical Network (PON), which provides service distribution to users over a simplified physical infrastructure. Because of these provided services, the development of industry standards covers a series of steps: from broadband passive optical network (Broadband-PON, B-PON) to Ethernet passive optical network (Ethernet-PON, E-PON), to gigabit Passive optical network (Gigabit-PON, G-PON), and ...
