A self-forming compact polymer waveguide for efficient chip-to-chip single-mode interconnection based on radiation mode coupling

Based on radiation mode coupling through a self-formed polymer waveguide extension, efficient single-mode optical coupling can be achieved between the active and passive chips while relaxing the stringent positioning requirements. A 20 dB improvement can be achieved according to simulation results.

Statistical analyses of two-dimensional photonic bandgap waveguides containing structural deviations

Feasibility studies and statistical analyses generated using specially tailored software tools of 2D photonic bandgap waveguides containing structural deviations are presented. Waveguide structures comprising two wide angle bends within a photonic bandgap structure were used in this analysis. The results demonstrate that small variations in the location and size of ordered media create significant changes in the photonic bandgap properties of the material. Deviations with a statistical mean of 20 nm in locaiton and size of this particular model designed for 1.55 μm wavelength are enough to cause the waveguide transmission to reduce by up to 90%.

Toward multifunctional optical integration: an adaptive lithographic method for patterning optical structures

A new method of interconnecting various optoelectronic components is discussed. Offset error up to 25 microns can be corrected to achieve single mode alignment accuracies. Several planar optical devices were photocomposed using the adaptive photolithographic method and these have been shown to perform with the desired characteristics.

A polymer-based platform technology for integrated photonics

Polymers have been studied as an alternate material to silica for optical interconnects and photonic devices for the last decade. In this paper we review the work performed at GE Global Research in the area of polymer based material systems for photonic applications. A description of the application of the technology to several different areas is presented. Some of these application areas include optical interconnects, optoelectronic integration and electro-optical devices using polymer material systems. The overall effort includes areas of research from the basic chemistry of polymer optical materials to the development of photonic components. Specifically the use of polymer materials as a platform technology for hybrid integration in the development of multi-functional sub systems is reviewed.

Radiation mode coupling between active and passive chips based on a self-formed compact polymer interconnect for single-mode chip-to-chip optoelectronic integration

Based on radiation mode coupling through a self-formed polymer waveguide extension, efficient single-mode optical coupling can be achieved between active and passive chips while relaxing the stringent positioning requirements. A 20dB improvement can be achieved according to simulation results. Single-mode waveguides have been successfully demonstrated using GE photo-definable polymer materials.

High-density multimode photonic backplane

The development of a photonic backplane for high-speed and high-bandwidth communications is presented. This hybrid, multimode, multi-channel backplane structure contains both electrical and optical interconnects, suitable for next-generation high-speed servers with terabit backplane capacity. Removable and all-passively aligned high density interconnects on this backplane are achieved by polymer based optical waveguides with integrated micro-optics and VCSEL arrays on conventional printed circuit boards. The fabrication of this photonic backplane requires few additional steps outside a traditional board-manufacturing environment and is largely compatible with existing processes.

Simulations and Statistical Analyses of the Alignment of Patterned Optical Waveguides

In this paper we investigate the tolerances required to achieve high transmission efficiencies given two planar waveguides with misalignments in both offset and overlap. More specifically, simulations of two types of waveguides, embedded and deep-ridge, with defects created during a multi-exposure lithographic process are presented along with statistical analyses results. Average efficiencies as high as 99% can be achieved with both waveguides having misalignment deviations in position as great as 0.3 μm. Overlap misalignment in the regime we explored was found to be much less critical for the planar waveguide coupling.Copyright
