Paper Abstract

The planar niicrolens (PML) is a 2-D integrated niicrolens array fabricated by the ion-exchange technique. This paper demonstrates light coupling between LD and optcal fiber using the planar inicrolens. In oder to accept the light power from LD effctively, two classes of High NA planar inicrolens are prepared. A coupled planar inicrolens and new planar inicrolens with swelled structure are evaluated. The minimum coulping loss between LD and single mode fiber was - 5.3 dB using planar muicrolens with the swelled stuctre. (Including 0. 71 dB of Fresnel loss)
