“…The mirrors were designed to have a maximum reflectivity at the central emission wavelength of the active region, i.e. k 0 = 620 nm which is the peak emission of the Alq 3 :DCM guest-host system [16]. The simulated transmission spectrum of the microcavity which is calculated using transfer matrix method (TMM) is shown in Fig.…”

We propose a low-threshold optically pumped organic vertical-cavity surface-emitting laser (OVCSEL). This device has the capability to apply both electrical and optical excitation. The microcavity structure consists of an organic light emitting diode with field-effect electron transport inserted in a high-quality factor double distributed Bragg reflector. The simulated quality factor of the microcavity is shown to be as high as 16,000. Also, we investigate threshold behaviour and the dynamics of the optically pumped OVCSEL with sub-picosecond pulses. Results from numerical simulation show that lasing threshold is 12.8 pJ/0.64 lJ cm -2 when pumped by subpicosecond pulses of k = 400 nm wavelength light.

“…In both cases the waveguides had a typical dimension of 100 μm and thus were clearly multimode, which is less relevant for biosensor applications. Punke et al managed to couple light from an optically pumped organic laser into PMMA‐based single‐mode waveguides 8…”

“…Although many researchers published results for discrete organic light‐emitting diode (OLEDs), organic field‐effect transistor (OFETs), and organic photodiode (OPDs) components, only recently the integration into monolithic systems has been explored. Examples include the combination of OFETs with OLEDs,2–4 OFETs and OPDs,5, 6 and OLEDs together with OPDs 7–9. The combination of OLEDs and OPDs is very promising for novel application areas such as chemical sensing,10–12 bio‐sensing,13, 14 or optical integrated systems 7…”

Evanescent coupling is used to couple light from an organic Lambertian emitter into a single-mode planar waveguide. A polymer light emitting diode pumps a photoluminescent layer located directly on top of the waveguide. At the out-coupling grating stage, a fully organic mini-spectrometer compatible with monolithical integration on optical bio chips has been developed. It consists of a single-mode waveguide with integrated diffraction grating and a dense array of polymer photodiodes as sensing element. An overall spectral resolution of down to 5 nm has been achieved with the integrated optoelectronic system. As a proof of principle the fully organic opti-cal device has been used in combination with a fluidic system to demonstrate an absorption-based bio-test with mouse immunoglobulin G. In a further step towards low-cost and disposable lab-on-chip biosensors, the mentioned organic building blocks have been combined with a surface plasmon stack integrated directly onto the single mode waveguide.

Organic photo detectors for an integrated thin-film spectrometer

We introduce a thin-film spectrometer that is based on the superprism effect in photonic crystals. While the reliable fabrication of two and three dimensional photonic crystals is still a challenge, the realization of one-dimensional photonic crystals as thin-film stacks is a relatively easy and inexpensive approach. Additionally, dispersive thin-film stacks offer the possibility to custom-design the dispersion profile according to the application. The thin-film stack is designed such that light incident at an angle experiences a wavelength-dependent spatial beam shift at the output surface. We propose the monolithic integration of organic photo detectors to register the spatial beam position and thus determine the beam wavelength. This thin-film spectrometer has a size of approximately 5 mm². We demonstrate that the output position of a laser beam is determined with a resolution of at least 20 µm by the fabricated organic photo detectors. Depending on the design of the thin-film filter the wavelength resolution of the proposed spectrometer is at least 1 nm. Possible applications for the proposed thin-film spectrometer are in the field of absorption spectroscopy, e.g., for gas analysis or biomedical applications.
