Paper Abstract

In this paper,analysis of a microlens arrays between fiber arrays an vertical cavity surface emitting laser arrays is reported with a variety of optical devices in transverse and vertical core pitch matching from 25 μm to 127 μm. Using 850nm wavelength 8 x 8 VCSEL arrays, we scale down the physical size in area from 4mm2 to 43 μm2 ,and minimize the longitudinal coupling length to 1.335mm. The optical power coupling efficiency can be increased above 90% with a flexible optical alignment range 30 μm of our proposed microlens arrays.It is necessary for the requirements of micro-optics package and minimized volume between fiber array and array chips.
