Author Affiliations +
The paper describes a new high NA planar microlens witha swelled structure (S- PML) designed for a laser diode (LD) array. The center to center spacing of the S-PML is 250 micrometers which is adjusted to the most ordinary LD array to be used in optical fiber communication system. The diameter of the S-PM is 85 micrometers and the focal length is 110 micrometers . The NA of the S-PML is 0.37. We evaluate the coupling loss between an LD and a single mode fiber using the S- PML. The coupling losses were 6.2 dB for 1.3 micrometers LD and 7.6 dB for 1.55 micrometers LD, respectively.
