Journal ArticleDOI
Interband cascade lasers
I. Vurgaftman,Robert Weih,Martin Kamp,Jerry R. Meyer,Chadwick L. Canedy,Chul Soo Kim,M. Kim,William W. Bewley,Charles D. Merritt,J. Abell,Sven Höfling,Sven Höfling +11 more
TL;DR: In this paper, the authors review the current status of interband cascade lasers (ICLs) emitting in the mid-wave infrared (IR) and discuss theoretical aspects of the active region and core designs, growth by molecular beam epitaxy, and the processing of broad-area, narrow-ridge, and distributed feedback (DFB) devices.
Journal ArticleDOI
Active tuning of surface phonon polariton resonances via carrier photoinjection
Adam D. Dunkelberger,Chase T. Ellis,Daniel Ratchford,Alexander J. Giles,Mijin Kim,Chul Soo Kim,Bryan T. Spann,I. Vurgaftman,Joseph G. Tischler,James Long,O. J. Glembocki,Jeffrey C. Owrutsky,Joshua D. Caldwell,Joshua D. Caldwell +13 more
TL;DR: In this article, a photoinjecting free carriers into nanoresonators was used to tune surface phonon polaritons (SPhPs) in InP and 4H-SiC by taking advantage of the coupling between the carrier plasma and optic phonons.
Journal ArticleDOI
Enhancement of Curie temperature in Ga1−xMnxAs/Ga1−yAlyAs ferromagnetic heterostructures by Be modulation doping
Tomasz Wojtowicz,W. L. Lim,Xiaofeng Liu,Margaret Dobrowolska,Jacek K. Furdyna,Kin Man Yu,Wladek Walukiewicz,I. Vurgaftman,Jerry R. Meyer +8 more
TL;DR: In this paper, the effect of modulation doping by Be on the ferromagnetic properties of Ga1−xMnxAs was investigated in Ga 1−xmnsxAs/Ga 1−yAlyAs heterojunctions and quantum wells.
Journal ArticleDOI
Enhancement of Curie temperature in Ga(1-x)Mn(x)As/Ga(1-y)Al(y)As ferromagnetic heterostructures by Be modulation doping
Tomasz Wojtowicz,W. L. Lim,Xiaofeng Liu,Margaret Dobrowolska,Jacek K. Furdyna,Kin Man Yu,Wladek Walukiewicz,I. Vurgaftman,Jerry R. Meyer +8 more
TL;DR: The effect of modulation doping by Be on the ferromagnetic properties of Ga(1-x)Mn(x)As is investigated in this article, where it is shown that the increase in Curie temperature occurs only in those structures where the modulation doping is introduced after the deposition of the magnetic layer, but not when the Be-doped layer is grown first.
Journal ArticleDOI
Midinfrared vertical-cavity surface-emitting laser
Christopher L. Felix,William W. Bewley,I. Vurgaftman,Jerry R. Meyer,Lew Goldberg,David H. Chow,E. Selvig +6 more
TL;DR: In this paper, a type-II antimonide midinfrared vertical-cavity surface-emitting laser is reported, with an emission wavelength of 2.9 μm that is nearly independent of temperature (dλ/dT≈ 0.07 nm).
