Abstract
A device for interferometric imaging may comprise multiple optical elements arranged in a linear configuration. The device may also comprise multiple waveguide arrays (WGAs) each WGA of the multiple WGAs may include one or more WGs. Some of the WGs of each WGA of the multiple WGAs may be optically coupled to an optical element of the multiple optical elements. Each WG of a first WGA of the multiple WGAs is coupled to a first optical element of the multiple optical elements and is paired with a WG of a second WGA of the multiple WGAs that is coupled to second optical element of the multiple optical elements. The lengths of the paired WGs of the first and second WGAs of the multiple WGAs are not equal.
