“…2), the transmissivity for a confined state can be as high as unity. That hints the EM wave can pass through the PQWS in a way similar to resonant tunneling of the electrons in a semiconductor QW structure [8]. One may also find that different incident lights can result in different electric field distributions, namely, three, two and one envelope oscillation peaks for the incident lights of 499, 547 and 605 nm, respectively.…”

Various combinations of periodically assembled nanoporous silicon layers with different refractive indices and thicknesses have been used to fabricate one-dimensional photonic quantum well structures, in which both the well and barrier regions consist of photonic crystals. The structures are operational in the regime of visible light. Quantized states resulting from the photonic confinement effect are observed, consistent with calculations using the transfer-matrix method. Behaviors of the photons in the structures can be well described by the effective wave-vector approach. It has been well established that, in analogy to the electrons in a quantum well (QW) or superlattice [1,2], the photons in a proper assembly of photonic crystals (PCs) with different band gaps are confined to quantized energy states, or referred to as being in a photonic quantum well structure (PQWS) [3 -10]. Early explorations in the millimeter-wave region gave rise to the emergence of two-and threedimensional PQWSs [3,4,9]. The transmissivity of a confined photonic state can be as high as unity, just like resonant tunneling of an electron through a semiconductor QW system. Obviously, the novel features of PQWSs are attractive for both fundamental and application studies.The simplest way to form a one-dimensional (1D) PQWS is to use a homogenous dielectric slab as the photonic well, sandwiched between two PCs as the photonic barriers [10]. But it is difficult to observe the photonic band gap (PBG) or QW effect in such a 1D PQWS and the structure arouses little interest actually [8]. Alternatively, a properly designed PC can be used as the well in a PQWS [7]. In that case, one may expect the QW effect observable and the number of the confined photonic states tunable by adjusting the number of the PC periods. This may lead to applications of the new structure in high-performance optoelectronic devices such as high-frequency PBG devices, multi-channel filters, etc. Further experimental investigation on the latter 1D PQWS is thus needed.In this communication, we report on realization of the structure by using porous silicon as the constituent material for all the PCs. The 1D PQWSs fabricated are operational in the regime of visible light and can be well described by the effective wave-vector approach [11,12] initially developed for description of the phonon confinement effect in the electronic QWs. The theoretically predicted [7] nonequivalence of the number of the confined photonic states with the photonic well periods in case that the photonic barrier does not completely confine a photonic band of the photonic well has also been experimentally confirmed.Exactly speaking, the porous silicon constituting the PCs studied in the present experiment is nanoporous silicon (nPSi) 1 , prepared by means of pulsed electrochemical etching [13].

“…Realizing the similarity between photon and electron, people have done the parallel research on the photon tunneling effects. For examples, the photon tunneling time measurement was proposed based on the analogies between electron and photon tunneling (Chiao et al 1991); various photon tunneling effect were investigated for the cases of supperlattice or negative refractive index materials, metal, and photonic crystal (Guan et al 2006;Han and Wang 2005;Garaia et al 2005;Jiang et al 1999).…”

Based on the well-known electron coherent tunneling phenomenon, by simulation, a photonic tunneling filter fabricated in an optical waveguide is proposed. The Bragg grating structure is applied as the photonic barrier. Two photonic barriers confine a coherent resonance cavity or photon-quantum-well. We report an asymmetric-barrier structure with opposite phase. In this configuration, the central tunneling wavelength is exactly the same as the Bragg wavelength of the grating, independent of the photon-quantum-well dimension. The photon-quantum-well length can be adjusted to make the tunneling peak interval fall to a desired spacing. The photon barrier length is responsible for the filter bandwidth. As an application, an asymmetric grating photon tunneling filter with International Telecommunication Union grid is demonstrated.

“…Electron energy is quantized in quantum well systems, including semiconductor quantum well, metal quantum wells, and quantum dots [5][6][7]. The photonic quantized states are not only seen in one-dimensional (1D) PC [4] but also in two-dimensional and threedimensional PC structures [8,9]. These photonic discrete states, which have a high transmittance because of the resonant tunneling, can thus be used to design an optical filter with multiple channels [10][11][12][13].…”

Abstract-Properties of wave transmission in a photonic quantum well (PQW) structure containing superconducting materials are theoretically investigated. We consider two possible PQW structures, (AB) P (CD) Q (AB) P -asymmetric and (AB) P (CD) Q (BA) P -symmetric, where the host photonic crystal (PC) (AB) P is made of dielectrics, A = SrTiO 3 , B = Al 2 O 3 , and the PQW (CD) Q contains C = A and superconducting layer D = YBa 2 Cu 3 O 7−x , a typical high-temperature superconducting thin film. Multiple transmission peaks can be seen within the photonic band gap (PBG) of (AB) P and the number of peaks is directly determined by the stack number of PQW, i.e., it equals Q-1. Additionally, the results show that symmetric PQW structure is preferable to the design of a multichannel transmission filter. The effect of stack number of photonic barrier is also illustrated. Such a filter operating at terahertz with feature of multiple channels is of technical use in superconducting optoelectronic applications.
