Investigation of coupling efficiency of optical fiber microlens / Suhaila Bahari

The project investigates the effective ways for coupling optical fiber to a laser diode. The study was very important in improving coupling efficiencies by using fiber microlens and the way to produce microlens. There are many ways to improved of coupling efficiency, one of the ways is by using microlens to increase the efficiency of coupling. This work on the project consists of getting the skill and experience on optical waveguide alignment system that has six degree of freedom. This project involved precision equipment and each equipment has their own characteristics and functions. One of the most important is work investigation on the technique of making fiber microlens. The result obtained from this project has improved coupling efficiencies using a fiber microlens coupled to laser diode.
