    Abstract: Optical cavities in a stacked organic light emitting device (SOLEDS) can shift or attenuate the light emitted by the individual organic light emitting devices (OLEDs) in the stack. Interference caused by reflections within the stack, absorption, positioning of the light source, and the polarization of the emitted light can all determine how the spectra of the emitted light are affected by the SOLED structure. A detailed model that provides a good fit to measured SOLED emissions can be used to predict how a SOLED will affect light emitted by OLEDs. As a result, SOLED geometries that will optimize color saturation and external quantum efficiency can be predicted.

    Abstract: Organic optoelectronic devices, such as a modulator (54) and a photodetector (73) comprising alternating layers (58) of two crystalline planar organic aromatic semiconductors (60 and 62), have been grown by organic molecular beam deposition. These organic substances have been deposited in ultra-thin layers only 10 .ANG. in depth using organic molecular beam deposition methods. Due to the anisotropic character of these organic materials,, the devices formed using these methods possess unique electronic and optical properties. The preferred embodiment of the invention utilizes 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) and 3,4,7,8-naphthalenetetracarboxylic dianhydride (NTCDA). While the inventors have identified PTCDA and NTCDA as excellent materials for the manufacture of organic optoelectronic IC devices, the broad scope of the present invention encompasses the use of any planar organic aromatic semiconductor which readily forms a crystalline structure. The preferred method of the invention employs a chamber (23) containing an inorganic substrate (32) with appropriate material for making electrical contact to the organic structures and sources of PTCDA (36) and NTCDA (38). The chamber (23) is maintained at a pressure which is generally less than 10.sup. -6 Torr. The substrate (32) is separated from the source materials by a minimum separation distance of 10 cm. The substrate (32) is held below 150K while the PTCDA and NTCDA are alternately heated. The methods described above may also be employed to fabricate an organic phototransistor/photodetector (78).

    Abstract: A high speed opto-electronic crossbar switch 10 disposed to selectively connect signals carried by first and second input optical beams to an output node 42. The inventive switch 10 includes a selectively actuatable photodetector network 22 for converting the signals carried by the first and second input beams to electrical output signals, and for impressing these output signals upon the output node 42. The photodetector network 22 has a first photodetector 30 in optical alignment with the first input beam, and a second photodetector 32 in optical alignment with the second input beam. The inventive crossbar switch 10 further includes a multiplexer 26 for actuating the first and second photodetectors 30, 32 in response to a control signal. The invention also includes a laser diode circuit 24 for illuminating the first and second photodetectors 30, 32 in response to the control signal.
