An apparatus for transporting and rejecting heat energy is provided. In one embodiment, the heat transporter includes a photonic microheatpipe and a source of photons. The photonic microheatpipe is a photonic crystal that shows pronounced Raman effect and is thermally coupled to a heat source. Photonic crystals disallow certain frequencies of light from being transmitted through the crystal. When a photon scatters back from phonons (lattice vibrations) in the crystal, the properties of the reflected spectrum are governed by the Raman effect. The reflected spectrum have two pronounced components: a Stoke's line and an Anti-Stokes line. The Stokes lines correspond to frequencies that are the difference between the frequency of the incident photons and that of the phonons, while the anti-Stokes lines correspond to frequencies that are sum of the frequency of the incident photons and that of the phonons. According to the present invention, the photonic crystal is selected such that the Stokes lines are suppressed while the anti-Stokes lines are not attenuated. Hence the photons reflected from the photonic crystal have frequencies (and energy) greater than the incident photons. Thus, heat energy represented as acoustic phonons is transferred into photons. The photons corresponding to the anti-Stoke lines are transmitted through the photonic microheatpipe away from the heat source to a suitable point for rejecting the heat energy.
