    • A scintillator detector of high-energy radiation comprising a semiconductor slab that is composed of alternating layers of barrier and well material. The barrier and well material layers are direct bandgap semiconductors. Bandgap of the well material is smaller than the bandgap of the barrier material. The combined thickness of the well layers is substantially less than the total thickness of said slab. The thickness of the barrier layers is substantially larger than the diffusion length of minority carriers. The thickness of the well layers is sufficiently large to absorb most of the incident scintillating radiation generated in the barrier layers in response to an ionization event from interaction with an incident high-energy particle.

    • In analyzing radiation from a communication link, single-photon counting can be used to advantage especially at low levels of radiation energy, e.g. in the detection of optical radiation. Preferred detection techniques include methods in which (i) received optical radiation is intensity-modulated in accordance with a preselected code, (ii) wherein it is the optical radiation which is intensity-modulated with the preselected code, and (iii) wherein the radiation modulated with a preselected code is received. For registration of the signals received by a sensing element of a single-photon detector, time of arrival is recorded, optionally in conjunction with registration of time intervals. Advantageously, in the interest of minimizing the number of pulses missed due to close temporal spacing of pulses, D-triggers can be included in counting circuitry.

    • A load sharing system which minimizes overall costs by assigning segments of a divisible load to distributed processor platforms based on the resource utilization cost of each processor platform. The distributed processor platforms are connected via data links which also have associated resource utilization costs. A controller divides a divisible load or task and assigns each segment of the load or task to a processor platform based on the processor platform's resource utilization cost and data link cost. After the initial allocation, an optimizing reallocation is performed to reduce the overall monetary cost processing the load or task. The optimization can be performed using a pair-wise swapping technique.

    • A semiconductor light source is disclosed comprising a substrate, lower and upper claddings, a waveguide region with imbedded active area, and electrical contacts to provide voltage necessary for the wavelength tuning. The active region includes single or several heterojunction periods sandwiched between charge accumulation layers. Each of the active region periods comprises higher and lower affinity semiconductor layers with type-II band alignment. The charge carrier accumulation in the charge accumulation layers results in electric field build-up and leads to the formation of generally triangular electron and hole potential wells in the higher and lower affinity layers. Nonequillibrium carriers can be created in the active region by means of electrical injection or optical pumping. Radiative recombination occurs between the electrons and holes, accumulated in the ground states of the triangular potential wells formed in the high- and low-affinity layers of each active region periods. The ground state energy in the triangular wells and the radiation wavelength can be tuned by changing the voltage drop across the active region.

    • Intersubband semiconductor lasers (ISLs) are of great interest for mid-infrared (2-20 &mgr;m) device applications. These semiconductor devices have a wide range of applications from pollution detection and industrial monitoring to military functions. ISLs have generally encountered several problems which include slow intrawell intersubband relaxation times due to the large momentum transfer and small wave-function overlap of the initial and final electron states in interwell transitions. Overall, the ISL's of the prior art are subject to weak intersubband population inversion. The semiconductor device of the present invention provides optimal intersubband population inversion by providing a double quantum well active region in the semiconductor device. This region allows for small momentum transfer in the intersubband electron-phonon resonance with the substantial wave-function overlap characteristic of the intersubband scattering.
    • Intersubband半导体激光器(ISL)对于中红外(2-20mum)器件应用非常有兴趣。 这些半导体器件具有从污染检测和工业监测到军事功能的广泛应用.ISL通常遇到几个问题,包括由于大的动量传递而引起的慢内插子带松弛时间,以及初始和最终电子的小波函数重叠 状态在井间转变。 总的来说,现有技术的ISL具有弱的子带内群体反转。本发明的半导体器件通过在半导体器件中提供双量子阱有源区域来提供最佳的子带间群体反转。 该区域允许子带内电子 - 声子共振中的小动量传递与子带间散射的基本波函数重叠特性。
