Abstract

The invention provides an integrated two-channel spectral combiner and a wavelength locker in silicon photonics. The two-channel DWDM spectral combiner integrated with a wavelength locker is provided. Two optical signals at ITU grid channels are separately modulated by MZM modulators and combined into a silicon waveguide-based delayed-line interferometer built on silicon-on-insulator substrate to produce a combined signal having a free spectral range equal to twice of the spacing of the two ITU grid channels. Two dither signals can be added respectively to the two optical signals for identifying corresponding two channel wavelengths and locking each wavelength while outputting the combined signal.

Description

technical field [0001] The present invention relates to optical telecommunication technology. More specifically, the present invention provides an integrated two-channel spectral combiner and waveguide-based wavelength locker within silicon photonics. Background technique [0002] Over the past few decades, with the advent of cloud computing and data centers, the needs of web servers have evolved. For example, the long-used three-level configuration is no longer adequate or appropriate because distributed applications require a flatter network architecture where server virtualization allows servers to operate in parallel. For example, multiple servers may be used collectively to perform requested tasks. The preoccupation of multiple servers running in parallel is often to quickly share large amounts of information among themselves, as opposed to moving data back and forth through a multi-layer network architecture (eg, network switches, etc.). [0003] Provides a leaf-and...
