Abstract
Disclosed herein is an apparatus, which comprises an optical waveguide, a first and second waveguide couplers. The optical waveguide may be configured to receive light from an end surface of the optical waveguide. The first waveguide coupler may be coupled, at a first coupling strength, to a first portion of the optical waveguide. The second waveguide coupler may be coupled, at a second coupling strength, to a second portion of the optical waveguide. Attenuation of the light at the first portion is smaller than attenuation of the light at the second portion. The first coupling strength is smaller than the second coupling strength. The first waveguide coupler and the second waveguide coupler each comprises a surface comprising sites configured to attach a probe.
