Abstract
The present invention relates generally to sensing devices. In an embodiment, the present invention provides a SPAD pixel that includes a first region and a second region. An absorption region is configured within the first region. A first reflector array is configured within the second region and below the absorption region. A second reflector array is configured within the second region and below the first reflector array. The SPAD pixel also includes isolation structures configured within the first region.
