Abstract: In summary, this SBIR program was highly successful, and a few modules were completely packaged for delivery to the JPL labs for further testing. We contacted the JPL team at a later stage. However, it appears that JPL team was not interested in taking delivery of these modules. However, a set of 32-channel WDM/WDDM modules were successfully used to demonstrate a high throughput bit-serial data transfers between two computers for another program. The main achievements of this program are: (1) The specifications, and finalized the device structure of the WDDM for bit-parallel computer architecture have been established. (2) A bulk ruled reflection high-order Echelle grating was employed to realize high dispersion, to achieve high diffraction efficiency within a wide spectral range, and low polarization dependent loss. A diffraction limited triplet lens was designed to serve for both of collimation and focusing simultaneously, so the device cost and size were decreased dramatically. (3) We also designed a 33-channel fiber array with non-uniform channel spacing to compensate the nonlinear effect of angular dispersion. (4) Graded index lensed fibers were designed and fabricated to expand the mode field diameter, and then to increase passband and alignment tolerance. (5) A thorough thermal analysis and optimization has been performed to achieve a thermalized WDM design and packaging. (6) In order to further broaden the passband to meet the specification, a 40 channel. (7) 100 GHz interleaver-based DWDM were designed and a prototype was built.
