Abstract
An optoelectronic apparatus includes a dual folding mirror, which is mounted on a carrier substrate and includes first and second reflecting surfaces disposed at opposite angles relative to a normal to the carrier substrate. First and second sensing devices are disposed respectively in proximity to the first and second reflecting surfaces. Each sensing device includes a planar substrate disposed on the carrier substrate and an array of sensing cells disposed on the planar substrate and including respective edge couplers disposed along the edge of the planar substrate so as to couple optical radiation between the sensing cells and the respective reflecting surface.
