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.
