Low-loss, Single-shot Fiber-Array to Chip Attach Using Laser Fusion Splicing

We present a novel technique for attaching up to 8 fiber arrays to a photonic chip in a single shot in less than a minute. We demonstrate a minimum loss of −1.4dB and −1.5dB per facet with a +/−0.2dB and 0.0dB variation through 8-fiber and 4-fiber arrays, respectively.
