Abstract
The invention relates to a bidirectional emitting and receiving module and includes a support having a top face and a bottom face, an emitting component disposed on the top face that emits light having a first wavelength, and a receiving component arranged on the bottom face that receives light having a second wavelength. The support includes a slanted boundary surface that is coated with a wavelength-selective mirror, and light emitted by the emitting component is reflected and deflected on the mirror, while light that is emitted by the emitting component and is to be received by the receiving component is refracted thereon into the adjacent medium. Such light is refracted on the boundary surface, penetrates the support, and leaves the support on the bottom face thereof, and is then detected by the receiving component.
