A new micro-lens array that is integrated into silica slab waveguides has been developed. This paper reports the design, material, fabrication, and performance of this new array. The micro-lens has a concave trench filled with a low refractive index polymer. The array has a low insertion loss (0.5 dB), low crosstalk (< -40 dB), and stable characteristics.
