Patent EP-0426239-A1 (EP)
Inventor: VERBEEK BASTIAAN HENDRIK
IPC: G02F1/35
Filed: 1990-10-24
Abstract: An optical amplifier with a semiconductor body comprising a layer structure grown on a substrate 1 with an active layer 4 situated between two cladding layers (2, 3) with a strip-shaped amplification region bounded by two end surfaces (7, 8) which form the input and output surfaces of the radiation to be amplified. The active layer comprises a number of quantum well (QW) layers 4A with direct band transition, which are separated by barrier layers 4B of a different semiconductor material. 
     According to the invention, the material, the number, and the thickness of the QW layers 4A and the barrier layers 4B in combination with the length  l  of the amplification region are chosen in such a way that two optical transitions can take place in the active layer 4, maximum amplification occurring at a certain current density through the PN junction for the radiation wavelengths corresponding to these optical transitions, while the end surfaces (7, 8) are provided with an anti-reflection layer 9 which has a reflection coefficient R of at most 0,5% for these two wavelengths. 
     An anti-reflection layer made up of four layers of alternately titanium oxide and aluminium oxide is advantageously used.

Abstract: A light source device that converts a beam of light radiated from an optical fiber-type second-harmonic generating element to a parallel beam of light filled with a bundle of rays up to a central portion of the parallel beam by causing a portion of the beam of light to pass through an apex of a conical surface. The light source device is unlikely to be affected by the spherical aberrations of members constituting an optical system such as lenses, which makes it unnecessary to make the component members of the optical system special, thereby simplifying the optical system.

Abstract: The system includes two transmitters (T1, T2) and two receivers (R1, R2). One transmitter (T1) includes a wavelength tunable laser, sending an FSK optical signal (OS1) which has a constant intensity. In a first receiver (R1) this FSK optical signal (OS1) is transformed into an IM signal (OS1') by an optical pass band filter. This IM signal (OS1') is then detected by a first direct detection receiver (DM). In a second direct detection receiver (R2) the FSK optical signal (OS2) is not detected, since it has constant intensity. A second transmitter (T2) includes a Fabry Perot laser or a LED with a broad linewidth, sending an IM optical signal (OS2). This IM optical signal (OS2) is detected by the second direct detection receiver (R2). It is not detected by the first direct detection receiver (DM), because it is strongly attenuated when passing through the narrow bandpass optical filter (TM) before being applied to the first direct detection receiver. This system is especially advantageous in bidirectional optical transmission systems, due to its inherent insensitivity for reflections.

Abstract: A fire fighting foam proportioner for use in providing precise proportioning of foam to fire fighting liquid, e. g. water, is disclosed. It includes a tank for the storage of foam concentrate which is loaded using a hand pump. The storage tank is coupled to a fire fighting line through a differential pressure responsive valve in the fire fighting line and a proportioning valve used to select the foam concentration desired, for example 0.2 to 1 percent of the fire fighting liquid. The differential pressure responsive valve applies discharge pressure to the foam concentrate as a function of the fluid flow through the line and therefore provides precise flow concentration maintenance despite changes if flow and line pressure. The differential pressure responsive valve includes to coaxial valving members and low and high pressure ports which are coupled to control the discharged pressure to the tank. The proportioner valve include a rotor with a continuous variable groove for precise control.
