Abstract
A fiber optic arrangement includes a chip, and a first light emitter and a second light emitter formed on the chip. A guide is formed on the chip and in registration with an active region of the second light emitter. An optical fiber is coupled to the second light emitter for transmitting light from the second light emitter. The guide aligns the optical fiber relative to the active region of the second light emitter. A light-sensing device is provided. An optical element transmits light emitted from the first light emitter to the light-sensing device for controlling an output optical power of at least the second light emitter.
