Based on the CROSSBAR network (CN) and the BANYAN network (BN) 8 matrix optical switch two new rearrangeable nonblocking constructions of extended BANYAN network (EBN) are proposed for implementing 88 optical matrix switch. The interconnection characteristics of these two types of rearrangeable nonblocking EBN were studied optical insertion loss of 4.6 dB and the logic program for driving switching units was provided. The calculated insertion loss was 3.3 dB for 88 optical matrix switch. Silica waveguide 88 matrix optical switch was designed and fabricated according to the calculated results. The silica waveguide propagation loss of 0.1 dB/cm and waveguide-fiber coupling loss of 0.5dB/point were measured. With the fabricated 87times cross-talk of -38 dB polarization dependent loss of 0.4 dB averaged switching power of 1.6 W and switching time of 1 ms were achieved. A basic agreement between experimental results and theoretical calculated values was achieved.

In this paper a new fabricating strategy for polymer microring resonators vertically coupled to a bus waveguide is developed. A carefully engineered Al masking process is utilized to compensate the local concave of the buried waveguide formed by polymer spin-coating realizing perfectly flat top surface of the buried bus waveguide. A serial of the vertically coupled polymer microring resonator showing excellent topology was fabricated with this strategy. The resonance phenomenon is oberved in a PMMA-based microring resonators using this fabricating strategy. The suggested approach is suitable to fabricate vertically coupled polymer micro-resonators.

A 32 32 arrayed waveguide grating (AWG) multiplexer operating around the 1550 nm wavelength has been designed and fabricated using fluorinated poly (ether ether ketone). The schematic layout is about 3.21.7 cm 2. For our AWG the total loss of designed AWG multiplexer is calculated to be 4.5 dB. We fabricated the AWG multiplexer by spin coating photolithographic patterning and reactive ion etching (RIE). The core size is 55 m2. The roughness of polymer surface was reduced by 20 nm using a remelting technique. The measured wavelength channel spacing of the fabricated AWG multiplexer is 0.796 nm and center wavelength is 1548 nm. The inserting loss of the AWG is 9.5 dB and crosstalk less than -20 dB.

Optical interconnection is the key technique of high-speed optical information process and optical communication. A lot of approaches for optical interconnection have been proposed since Goodman in Stanford University firstly proposed the optical interconnection for very large scale integrated circuits technology. A dynamical addressing device for optical interconnection was designed and fabricated in this paper. This optical device is based on one-dimensional nonlinear photonic crystal made on the planar waveguide. The nonlinear materials ZnS and ZnSe which have large nonlinear refractive index coefficients were alternately deposited on the waveguide to form one-dimensional photonic crystal. The Bragg condition is changed when the input power of the control light increased due to the nonlinear characters of the materials thus the reflective angle of the signal light can be changed with the input power change of the control light. In our experiment when increasing the power density of control light from 0 to 2.60X105W/cm 2 the angle of the signal beam can be changed about 20. The interconnection characteristics were investigated in theory and in experiment. The testing data agree well with theoretical predictions. This kind of devices is promising to use in the all-optical interconnection optical information processing and optical communication.

Future optical communication systems will use more of the exceptional high bandwidth of optical fiber. Wavelength division multiplexing (WDM) systems are well suited to transport terabits of information via the fiber[1]. Multiplexers/ demultiplexers (MUX/DEMUX) are essential components for dense WDM systems. Several different kinds of multiplexer types have been developed in the past: (a) interference filters (b) fiber gratings and (c) planar lightwave circuit (PLC) MUX/DEMUXers[2 3]. The planar fabrication process of the last mentioned PLCs allows the realization of high performance filters with a large number of wavelength channels. Further an integration with other optical elements seems to be possible. Arrayed waveguide gratings (AWG) are a special kind of PLC-MUX/DEMUXers which are very attractive components for WDM systems because of their great flexibility in filter design[4 5]. Basically an AWG is an optical spectrograph built in planar waveguide technique. Typically AWGs works in a high grating order (50-250). For AWG multiplexer applications in communications systems a precise wavelength controllability and wavelength stability with long term is demanded. Recently a polymeric (especially fluorinated polymer with low optical absorption loss in the infrared region) AWG has attracted much attention because of its easy fabrication low cost possibility and a potential of integration with other polymer devices[6]. Standard AWGs however show a change of center wavelength with temperature. A method to prevent this temperature drift is to package the AWG together with a temperature controller in order to tune and fix the desired filter-wavelength. In this paper a 32-channel AWG was fabricated using a cross-linkable fluorinated poly (ether ether ketone) (FPEEK) its package technology and environmental stability were also discussed. 2005 IEEE.
