A miniature photonic system is a technological revolution in the making. We are participating in this revolution as one of our major research projects is based on this theme. Miniaturized integrated photonics, and their use for spectroscopy is one of our core expertise.

Integrated electronic circuits, as in our cell-phones, are well-known examples of a monolithic integration where several electronic components and functionalities are miniaturized, integrated and fabricated together on a single substrate, thereby simultaneously reducing the size, inefficiencies and cost of the integrated system. With the advent of integrated photonic devices such as laser diodes, a white light emitting diode (LED), infrared (IR) sensors and CMOS cameras embedded in our mobile phones, the complexity and opportunities with the integrated photonic components are remarkably growing. This has opened up several applications in telecom, and biochemical sensing and other consumer goods. Following are few recent publications on integrated photonic sensors, wherein the scientists of this institute has made a major contribution, hence bears the name of this institute.

Phutung Research Institute established in international community of scientists.

The crosssection

Within a few months of its establishment, our institute has participated and contributed for publication of a scientific study about the nature of scattering of light guided in a very small structures (in the nanometer scale). The research has been published in a peer-reviewed international journal called Materials reputed in the field publishing high impact papers. Please read the paper for details by following this link. Please note our institute is among one of the contributing institutions.

One of our scientists, Dr. Ashim Dhakal has recently published a peer-reviewed journal paper in a reputed journal ACS Photonics about a research on the integrated photonics he conducted in the University of Ghent, Belgium. In this work he showed that photonic structures at the nanoscale has a very high sensitivity for spectroscopy compared to traditional approaches using a microscope. Hence, can be used to observe biochemical reactions, such as hybridization of DNA, in the real time. Please read the paper by following this link
