Исследована зависимость затухания собственной оптической моды вертикально-излучающего лазера с внутрирезонаторными металлическими контактами от геометрических параметров системы. Показано, что наименьшее затухание имеет место для частоты собственной моды резонатора, отличной от брэгговской частоты зеркал. Методом S-квантования рассчитана вероятность спонтанной эмиссии, и показано, что для высокоэнергетической нечетной моды вероятность спонтанной эмиссии увеличивается на 2 порядка по сравнению с вероятностью эмиссии в свободном пространстве.

“…Such modes have been predicted theoretically, 11,12 observed experimentally in organic microcavities, 13 and recently shown coherent behaviour such as lasing, 14 or utilized in a silver grating to investigate macroscopic phase-locking. 15 Structuring is again possible via photolithography, either by utilizing a lift-off process or by wet chemical etching of the silver.…”

Threshold reduction by multidimensional photonic confinement in metal-organic microcavities

et al. 2014

Due to their geometry, optical microcavities allow strong confinement of light between the mirrors and promise single mode operation at lowest possible lasing thresholds. Nevertheless, such devices suffer from losses not only due to parasitic absorption of the active or mirror layers, but especially via outcoupling of leaky and waveguided modes within the active layer.In this work, we present an organic microcavity sandwiched between high quality dielectric distributed Bragg reflectors. A highly conductive silver layer of 40 nm thickness is added next to the active layer, leading to the formation of Tamm-Plasmon-Polaritons (TPP), one replacing the original cavity mode and shifting its resonance to the red, another one emerging from the long-wavelength sideband and moving to the blue. To avoid parasitic absorption introduced by such contacts, the silver layer is structured on the micrometer-scale using photolithography, yielding seperated areas supporting either original cavity mode or red shifted TPP-resonances. This separation leads to a strong spatial trapping of the modes to only their resonant regions on the sample and can in turn be exploited to achieve complete three-dimensional confinement of photons.In elliptic holes produced in the metal layer, we observe the formation of Mathieu-Modes, leading to a reduction of the lasing threshold by six times. Facilitating triangular cuts in the silver layer, highly confined standing modes develop in the system, allowing a precise optimization of the spatial mode extension and reducing the threshold even further down to one order of magnitude below the threshold of an unstructured organic cavity.These results show that the introduction of absorptive metals, needed for the realization of an electrically driven laser, can in turn be harnessed to improve the characteristics of the device.

“…So far, efforts have mainly been focused on time-integrated and time-resolved studies of the emission under nonresonant excitation. Thereby, the Purcell effect of single QD excitons coupled to a localized TP mode [12], enhancement of the spontaneous emission [13], and coherent laser emission [10,14] were demonstrated.…”

“…Furthermore, the metal mirror may be used as an electrode to apply a bias voltage to control the charging state of the QDs or to pump the optically active layer electrically [8]. As active materials in the resonator single or multiple quantum well (QW) [8][9][10][11] or QD [12,13] layers as well as organic materials [14,15] and single layers of transitiion * matthias.salewski@tu-dortmund.de metal dichalcogenides [16] were used. So far, efforts have mainly been focused on time-integrated and time-resolved studies of the emission under nonresonant excitation.…”
