| Abstract | We review our experimental work on the generation of microwave (MW), millimeter-wave (MMW) and THz signals using a 1310-nm Quantum Dot (QD) Distributed-Feedback (DFB) laser. Continuous tunable MW signals with frequencies going from below 1 GHz to over 40 GHz are generated by means of the period-1 dynamics induced in the QD DFB laser when subject to external optical injection into the device's lasing mode. A new technique is also reported for the generation of MMW and THz signals with an optically-injected 1310nm-QD DFB laser. This technique is based on the dual-mode lasing and Four-Wave-Mixing arising in the QD laser under single-beam optical injection into one of its subsidiary Fabry-Perot (FP) modes. Tunability of the generated MMW and THz signals from 117 GHz to 954 GHz is also demonstrated. Coarse tunability is achieved by injecting the external light into different residual FP modes of the device, whilst fine tuneability is obtained by controlling the initial frequency detuning. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
