摘要： The disclosed embodiments provide a tunable laser that includes a set of M reflective silicon optical amplifiers (RSOAs) and a set of N narrow-band reflectors. It also includes a silicon-photonic optical switch, having M amplifier ports, which are coupled through a set of M optical waveguides to the set of M RSOAs, and N reflector ports, which are coupled to the set of N narrow-band reflectors. The tunable laser also includes a switching mechanism that facilitates coupling at least one selected amplifier port from the M amplifier ports with a selected reflector port from the N reflector ports, thereby causing an RSOA coupled to the selected amplifier port to form a lasing cavity with a narrow-band reflector coupled to the selected reflector port. The tunable laser also includes a laser output, which is optically coupled to the lasing cavity.

摘要： We disclose an optical buffer having a plurality of optical ports. In some embodiments, an optical signal to be stored may be injected into the buffer through any one of the optical ports and then may be ejected from the buffer, after being stored therein for a selectable amount of time, through any one of the optical ports as well. This feature advantageously enables the optical buffer to also function as an optical switch or router. In an example embodiment, the optical buffer comprises two optical recirculation loops, each of which can store the optical signal by causing it to circulate therein. The buffer is configured to compensate optical losses incurred by the optical signal during this circulation by transferring the optical signal from one loop to the other through an optical amplifier. Due to the latter feature, the optical buffer may be able to store an optical signal, with an acceptable OSNR, for a significantly longer time than certain conventional optical buffers.
