摘要： A laser diode device comprises a layered structure, and defines two upper contact regions to which bias current signals can be applied. A first contact region receives a fist bias signal and a modulating signal. Such a device can produce a light output signal which can be modulated at high frequency using a low modulating current swing and can operated in uncooled conditions, whilst giving satisfactory output characteristics compared with single contact devices.

摘要： Optical radiation is applied to a multimode optical fibre, either from another fibre or from a laser, in such a way as to control the mode distribution in the multimode optical fibre. The mode distribution is selected in such a way as to improve performance, for example to avoid transmission nulls or to reduce noise due to reflections back to a laser.

摘要： A method of transmission of radio signals over all types of graded-index multimode fibre is provided. The method comprises launching optical radiation into the core of the multimode fibre with a specified restricted launch to allow multiple transverse mode lasers transmitters to be used in low cost radio over fibre links. The launch technique allows a reduction in modal dispersion and modal interference, thus greatly improving the transmission performance of radio over fibre signals over multimode fibre as well as reducing system impairments such as outages and link failures.

摘要： A method is provided for the transmission of digital and radio frequency signals, for example for multiservice applications, over all types of multimode optical fibre link using laser diodes. The method comprises launching optical radiation into the core of the multimode optical fibre, in a manner that restricts the number of excited modes within it. The subset of modes that are excited suppress additional noise due to the presence of a multiplicity of signals, and ensure high quality transmission.

摘要： An optical transducer for determining distance or displacement of a mirror (3) comprises a laser diode (1) which is excited at constant current. The spectrum of the voltage signal across this laser diode is analysed and the spacing between this laser diode and the mirror (3) is determined from the formula f = cm/2L where f is the frequency; c is the speed of light; m is the mode number and L is the effective optical length of the cavity. A force or other transducer can be coupled to the mirror (3) to enable force or other parameters to be determined. In another embodiment the laser beam is conducted to a remote optical cavity of variable length by an optic fibre and the frequencies in the remote cavity are measured by analysing the voltage signal across the laser diode.

摘要： A semiconductor laser has an optical cavity formed between a pair of reflecting surfaces and a region or regions having a non-uniform cross section with a minimum value at a predetermined location between the reflecting surfaces so that the optical energy at both surfaces is distributed over a broader area and hence the optical intensities at the facets are reduced. The tapered bow-tie structures have a sufficiently gradual change to ensure adiabatic spatial mode-shape variation permitting single spatial mode operation. The laser is also used for Q-switching or mode-locking.

摘要： A method and an apparatus are provided for launching light into an entrance facet of a MMF of an optical MMF link in a way that excites one or more targeted higher-order mode groups in the MMF. The light is launched into the entrance facet of the MMF as a line of phase- modulated spots, referred to herein as a "line launch". The line launch causes one or more targeted higher-order mode groups to be excited in the MMF. The use of the line launch to excite one or more higher-order mode groups in the MMF increases the bandwidth of the link and allows overall link lengths to be increased. In addition, the use of the line launch is reliable and robust despite defects in the MMF and despite connector offsets. Thus, the use of the line launch ensures that a sufficient increase in link bandwidth will be achieved despite the existence of defects in the MMF and even if there is some amount of optical misalignment due to the connector being offset relative to the corresponding receptacle.
摘要翻译：提供了一种方法和装置，用于以激励MMF中的一个或多个目标高阶模式组的方式将光发射到光学MMF链路的MMF的入口面。光线作为一系列相位调制点发射到MMF的入口面，这里被称为“线路发射”。线路发射导致一个或多个有针对性的高阶模式组在MMF中激动。使用线路发射来激励MMF中的一个或多个高阶模式组增加了链路的带宽，并允许增加整体链路长度。此外，尽管MMF中存在缺陷，并且尽管连接器偏移，使用线路发射是可靠和稳定的。因此，线路发射的使用确保尽管存在MMF中的缺陷并且即使由于连接器相对于相应的插座偏移而导致一定量的光学未对准，仍将实现链路带宽的充分增加。

摘要： A hub for use in an optical communication system receives, combines and distributes signals including radio frequency and baseband digital signals over an optical fibre communication system. Embodiments of the invention restrict the set of modes launched into the optical fibre, for example, by preventing very high order modes and/or very low order modes from being excited in the fibre or by limiting the amount of power in these mode groups relative to other mode groups.
