Abstract
High coupling efficiency with passive alignment of cylindrical microlens fiber fabricated by photocurable resin with simple process to achieve desired lens structure is presented. Optimal lens dimensions of 4-
$\mu $
m upper base, 9-
$\mu $
m lower base, and 12-
$\mu $
m height were determined by simulation software. Despite mode conversion losses, maximum coupling efficiency reached 71.2%. Experimental results closely matched simulations of 67.6% coupling efficiency. A
$1.5~\mu $
m offset in the X-Y plane, defined within a Cartesian coordinate system, resulted in a measured 3-dB efficiency drop. Compared to microlens fiber with grinding processes, the microlens fibers offer improved efficiency and tolerance. The proposed microlens fibers with array setups could reduce alignment time and cost during packaging, suggesting applications in silicon light modules, optical radar, and biomedical measurements.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
