| Research Abstract |
This research aims to develop an optical network processor for an optoelectronic parallel computing system based on a parallel computing architecture called OAL-NC (optical array logic network computing). The obtained results are as follows :
1. For design of the discrete correlator for the OAL-NC network processor, an effective method based on automatic-lens design and substitution of commercially available lenses has been developed. With the method, a small-distortion optical system has been designed consisting of 6 lenses.
2. The designed optical system has been constructed and its performance were verified. Due to broad emission of the light emitting diodes, optical power efficiency was only 0.0005%, which suggests requirement of redesign of the system.
3. For the prism array of the discrete optical correlator, a fabrication technique using photo-sensitive polymer with a Twyman-Green interferometer has been developed. The attained precision was 2 degree for the top angle.
4. Operational characteristics of the discrete correlator has been evaluated in the OAL-NC experimental system (16 x 16 pixel system). XOR logic was successfully executed in the context of optical array logic.
5. For integration of optical systems, a discrete correlation module has been constructed using photo-sensitive polymer. The optical system is composed of two lenses with 15mm diameter and 21.8mm focal length and a prims array. Optical resolution of the module is 16 lp/mm.
