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.

An optoelectronic apparatus, comprising:
- a carrier substrate;
- a dual folding mirror mounted on the carrier substrate and comprising first and second reflecting surfaces disposed at opposite angles relative to a normal to the carrier substrate;
- a first sensing device, comprising:
- a first planar substrate disposed on the carrier substrate with a first edge of the first planar substrate in proximity to the first reflecting surface;
- and
- a first array of first sensing cells disposed on the first planar substrate and comprising respective first edge couplers disposed along the first edge of the first planar substrate so as to couple optical radiation between the first sensing cells and the first reflecting surface;
- and
- a second sensing device, comprising:
- a second planar substrate disposed on the carrier substrate with a second edge of the second planar substrate in proximity to the second reflecting surface;
- and
- a second array of second sensing cells disposed on the second planar substrate and comprising respective second edge couplers disposed along the second edge of the second planar substrate so as to couple optical radiation between the second sensing cells and the second reflecting surface.
A method for optical sensing, comprising:
- mounting on a carrier substrate a dual folding mirror comprising first and second reflecting surfaces disposed at opposite angles relative to a normal to the carrier substrate;
- placing on the carrier substrate a first sensing device comprising a first planar substrate and a first array of first sensing cells disposed on the first planar substrate and comprising respective first edge couplers disposed along a first edge of the first planar substrate, such that the first edge of the first planar substrate is in proximity to the first reflecting surface, whereby the first edge couplers couple optical radiation between the first sensing cells and the first reflecting surface;
- and
- placing on the carrier substrate a second sensing device comprising a second planar substrate and a second array of second sensing cells disposed on the second planar substrate and comprising respective second edge couplers disposed along a second edge of the second planar substrate, such that the second edge of the second planar substrate is in proximity to the second reflecting surface, whereby the second edge couplers couple optical radiation between the second sensing cells and the second reflecting surface.
