Abstract: In one embodiment of a superluminescent diode, a first diode adapted on a semiconductor die is to be forward-biased to output optical energy in response to a bias signal, and a second diode adapted on the semiconductor die is to be reverse-biased, the second diode to receive and absorb back propagating optical energy from the first diode and output a measure of the back propagating optical energy as an absorber feedback current. A comparator may be configured to compare the absorber feedback current to a reference current and output a comparison signal, and a driver control circuit coupled to the comparator may provide the bias signal based at least in part on the comparison signal. Other embodiments are described and claimed.

Abstract: Embodiments of the present disclosure are directed to multi-wavelength laser generator may produce light with a frequency comb having equally spaced frequency lines. In various embodiments, the laser generator includes first, a semiconductor gain element is used to provide gain to the laser being generated. Second, a ring resonator filter, or ring filter, is used to select the wavelength comb spacing. Third, a narrow-band DBR or narrow-band mirror is used to select the number of wavelengths that lase. Fourth, a wide-band or narrow-band mirror is used to provide optical feedback and to form the optical cavity. Fifth, a phase tuner section is used to align the cavity modes with the ring resonances (i.e. the ring filter modes) in order to reduce or minimize the modal loss. Other embodiments may be described and/or claimed.
