| Abstract | This study demonstrated a use of photonic crystal directional coupler to separated two lights of 1.3 /spl mu/m and 1.55 /spl mu/m wavelength. The photonic crystal structure consists of the InAlGaAs nano-rods arranged in square-shaped lattice, and the device was fabricated by the electron beam lithography. For the measurement results, the optical power extinction ratio between the 1.3 /spl mu/m and 1.55 /spl mu/m output ports are 10 dB and 17 dB, respectively. This behavior helps in designing devices to split two wavelengths, and the measurement results confirm that 1.3/1.55 /spl mu/m directional coupler can be realized in the photonic crystal. Additionally, the defect shifting effect was also discussed in this study. By moving a defect lattice near the bend region appropriately, the transmission loss could be reduced significantly. Therefore this effect can be considered into the design of the photonic crystal directional coupler to improve the device performance. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
