Abstract: An apparatus comprising a burst-mode laser(610) comprising an active layer(720) and configured to emit an optical signal during a burst period, wherein a temperature change of the burst-mode laser(610) causes the optical signal to shift in wavelength, and a heater(620) thermally coupled to the active layer(720) and configured to reduce a wavelength shift of the optical signal during the burst period by applying heat to the active layer(720) based on timing of the burst period.

Abstract: An adaptive heat dissipation apparatus is provided, including two or more chamber walls forming a chamber volume having a first open side and a second open side, a heat source positioned at the first open side of the chamber volume, a heat conducting surface positioned at the second open side of the chamber volume, and a thermally-expansive material occupying a predetermined portion of the chamber volume. The thermally-expansive material expands to substantially fill the chamber volume at an ambient temperature above a predetermined temperature threshold and conducts heat from the heat source to the heat conducting surface. The thermally-expansive material contracts to leave an air gap when the ambient temperature is below the predetermined temperature threshold.

Abstract: An optical splitter (200) has a main branch (222) coupled to a number of tributary branches (224-226). The main branch (222) includes a light-absorptive core (230) and a light-reflective grating (232). The absorptive core (230) can absorb light (313) arriving from the tributary branches (224-226) and transmit light (302) arriving from the main branch (222) to the reflective grating (232). The reflective grating (232) can reflect light (302) from the main branch (222) back through the absorptive core (230) to the main branch (222). Light (313) arriving from the tributary branches (224-226) exchanges mode with light (304) reflected by the reflective grating (232).
