Microlens arrays for interconnection of singlemode fibre

The efficient coupling of light between arrays of singlemode optical fibres has been demonstrated using arrays of refractive microlenses. The arrays are highly uniform in both spacing and the optical properties of the individual lenses. These lenses have little chromatic aberration, and concurrent operation at wavelengths of 1308 nm and 1540 nm has been demonstrated.lt;lt;ETXgt;gt; Get price

Fabrication of Random Microlens Array for Laser Beam

The miniaturized and integrated microlens array (MLA) can effectively achieve the beam homogenization, compactness and miniaturization of laser systems. When the high-coherence laser beam is homogenized by means of using the MLA, interference fringes will occur in the homogenized light spot due to the periodicity of the MLA, which seriously affects the uniformity of the homogenized Get price
