Tailoring high-temperature radiation and the resurrection of the incandescent source.

Nature nanotechnology

Ilic O, Bermel P, Chen G, Joannopoulos JD, Celanovic I, Soljačić M.
PMID: 26751172
Nat Nanotechnol. 2016 Apr;11(4):320-4. doi: 10.1038/nnano.2015.309. Epub 2016 Jan 11.

In solar cells, the mismatch between the Sun's emission spectrum and the cells' absorption profile limits the efficiency of such devices, while in incandescent light bulbs, most of the energy is lost as heat. One way to avoid the...

Laser-Induced Linear-Field Particle Acceleration in Free Space.

Scientific reports

Wong LJ, Hong KH, Carbajo S, Fallahi A, Piot P, Soljačić M, Joannopoulos JD, Kärtner FX, Kaminer I.
PMID: 28894271
Sci Rep. 2017 Sep 11;7(1):11159. doi: 10.1038/s41598-017-11547-9.

Linear-field particle acceleration in free space (which is distinct from geometries like the linac that requires components in the vicinity of the particle) has been studied for over 20 years, and its ability to eventually produce high-quality, high energy...

Optically Thin Metallic Films for High-Radiative-Efficiency Plasmonics.

Nano letters

Yang Y, Zhen B, Hsu CW, Miller OD, Joannopoulos JD, Soljačić M.
PMID: 27244596
Nano Lett. 2016 Jul 13;16(7):4110-7. doi: 10.1021/acs.nanolett.6b00853. Epub 2016 Jun 10.

Plasmonics enables deep-subwavelength concentration of light and has become important for fundamental studies as well as real-life applications. Two major existing platforms of plasmonics are metallic nanoparticles and metallic films. Metallic nanoparticles allow efficient coupling to far field radiation,...

Composite multihump vector solitons carrying topological charge.

Physical review letters

Musslimani ZH, Segev M, Christodoulides DN, Soljacic M.
PMID: 11017469
Phys Rev Lett. 2000 Feb 07;84(6):1164-7. doi: 10.1103/PhysRevLett.84.1164.

We propose composite solitons carrying topological charge: multicomponent two dimensional [ (2+1)D] vector (Manakov-like) solitons for which at least one component carries topological charge. These multimode solitons can have a single hump or exhibit a multihump structure. The "spin"...

Modulation instability of incoherent beams in noninstantaneous nonlinear media.

Physical review letters

Soljacic M, Segev M, Coskun T, Christodoulides DN, Vishwanath A.
PMID: 11015940
Phys Rev Lett. 2000 Jan 17;84(3):467-70. doi: 10.1103/PhysRevLett.84.467.

We show that modulation instability can exist with partially spatially incoherent light beams in a noninstantaneous nonlinear environment. For such incoherent modulation instability to occur, the value of the nonlinearity has to exceed a threshold imposed by the degree...

Integer and fractional angular momentum borne on self-trapped necklace-ring beams.

Physical review letters

Soljacić M, Segev M.
PMID: 11177845
Phys Rev Lett. 2001 Jan 15;86(3):420-3. doi: 10.1103/PhysRevLett.86.420.

We present self-trapped necklace-ring beams that carry and conserve angular momentum. Such beams can have a fractional ratio of angular momentum to energy, and they exhibit a series of phenomena typically associated with rotation of rigid bodies and centrifugal...

Modulation instability and pattern formation in spatially incoherent light beams.

Science (New York, N.Y.)

Kip D, Soljacic M, Segev M, Eugenieva E, Christodoulides DN.
PMID: 11039925
Science. 2000 Oct 20;290(5491):495-8. doi: 10.1126/science.290.5491.495.

We report on the experimental observation of modulation instability of partially spatially incoherent light beams in noninstantaneous nonlinear media and show that in such systems patterns can form spontaneously from noise. Incoherent modulation instability occurs above a specific threshold...

Color of shock waves in photonic crystals.

Physical review letters

Reed EJ, Soljacić M, Joannopoulos JD.
PMID: 12785897
Phys Rev Lett. 2003 May 23;90(20):203904. doi: 10.1103/PhysRevLett.90.203904. Epub 2003 May 23.

Unexpected and stunning new physical phenomena result when light interacts with a shock wave or shocklike dielectric modulation propagating through a photonic crystal. These new phenomena include the capture of light at the shock wave front and reemission at...

Nonlinear photonic crystal microdevices for optical integration.

Optics letters

Soljacić M, Luo C, Joannopoulos JD, Fan S.
PMID: 12703925
Opt Lett. 2003 Apr 15;28(8):637-9. doi: 10.1364/ol.28.000637.

A four-port nonlinear photonic crystal system is discussed that exhibits optical bistability with negligible backscattering to the inputs, making it particularly suitable for integration with other active devices on the same chip. Devices based on this system can be...

Interactions between two-dimensional composite vector solitons carrying topological charges.

Physical review. E, Statistical, nonlinear, and soft matter physics

Musslimani ZH, Soljacić M, Segev M, Christodoulides DN.
PMID: 11415243
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Jun;63(6):066608. doi: 10.1103/PhysRevE.63.066608. Epub 2001 May 23.

We present a comprehensive study of interactions (collisions) between two-dimensional composite vector solitons carrying topological charges in isotropic saturable nonlinear media. We numerically study interactions between such composite solitons for different regimes of collision angle and report numerous effects...

Cavity pattern formation with incoherent light.

Physical review. E, Statistical, nonlinear, and soft matter physics

Buljan H, Soljacić M, Carmon T, Segev M.
PMID: 12935279
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Jul;68(1):016616. doi: 10.1103/PhysRevE.68.016616. Epub 2003 Jul 29.

We study the propagation dynamics of an incoherent light beam circulating in a passive cavity containing noninstantaneous nonlinear media. It is shown that patterns form in this cavity in spite of spatial incoherence of the light. We show that...
