Abstract
An array of optical devices includes singlets diced or separated from a first diced surface and a second diced surface of a semiconductor wafer. Each singlet includes a single optical emitter or a single photosensitive semiconductor device. The singlets are identified as operationally fit before being arranged in corresponding features in a receiving region of a submount. The corresponding features of the submount are arranged to align and precisely control the pitch or separation distance between optical portions of a desired number of singlets. The use of operationally fit singlets dramatically increases production efficiency as it is no longer necessary to identify N contiguous operational optical devices in a semiconductor wafer to produce a precisely aligned array of N operational optical devices.
