Packet-selective Photonic Add/Drop Multiplexer and Its Application to Ultrahigh-speed Optical Data Networkings in LAN and MAN
نویسندگان
چکیده
We propose p acket-selective photonic add/drop multiplexing (P-ADM), which can determine the source and de stination addresses in the packet header based upon optical code correlation and its novel application to ultrahighspeed optical data networking in LAN and MAN. It is distinct from conventional wavelength ADM (λ-ADM) in the traffic granularity, in that P-ADM can individually handle the packets while λ-ADM handles the whole traffic together on a single wavelength. As an application of P-ADM to optical data networking, a rate-controlled asynchronous access is studied, and the performance analysis and n umerical examples are presented. The optical implementation of P-ADM is also presented, in which the photonic label selector, structured with a fiber Bragg grating (FBG), is a key to the ultrahigh -speed processing capability up to a few tens of Gpps (packet per second).

Add-Drop and Channel-Drop Optical Filters Based on Photonic Crystal Ring Resonators
Here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. These structures are made of a square lattice of silicon rods with the refractive index n1=3.464 surrounded by air (with refractive index n2=1). The broadest photonic band gap occurs at the filling ratio of r/a = 0.17. Two linear defect W1 waveguides couple to the ring....

We report on a channel drop filter with a mode gap in the propagating mode of a photonic crystal slab that was fabricated on silicon on an insulator wafer. The results, simulated with the 3-dimensional finite-difference time-domain and plane-wave methods, demonstrated that an index-guiding mode for the line defect waveguide of a photonic crystal slab has a band gap at wave vector k = 0.5 for a ...

Silicon photonic-wire waveguide is one of the most promising platforms in constructing compact optical devices, since the waveguide can be bent with a radius of less then several microns. Recently, we have demonstrated various optical devices based on silicon photonic-wire waveguides, which include a directional coupler, a tunable optical add-drop multiplexer, and some ultra-compact 1 x N optic...
