Abstract: An optical circuit comprises a bistable optical waveguide (34) having a first and a second transmission state. The waveguide is more transmissive to light of a given wavelength in the second state than in the first state. A first light source (11) and a second light source (21) emit light of a first and second wavelength respectively and are coupled to the waveguide at one end. Selective transmission of a sufficient amount of light of the first wavelength through the waveguide "sets" the waveguide, causing it to switch from the first into the second state, whereas transmission of a sufficient amount of light of the second wavelength "resets" the waveguide causing it to switch back from the second into the first state. A sensing or reading ("test") light source (36) is arranged at the other end of the waveguide to transmit a sensing light signal through the waveguide (34) in the opposite propagation direction to that of light of the first and second wavelengths. This sensing light source can be an external light source or an "internal" source provided by spontaneous emission in the waveguide. A sensor (38) is arranged to detect the amount of the sensing light signal transmitted through the waveguide (34). In this way the waveguide can be set into a given transmission state, which can be determined at a later time by measuring the amount of the sensing light signal transmitted. The optical circuit therefore exhibits a memory effect and may be used to produce an all-optical bistable logic circuit such as an optical latch or an optical flip-flip. Typically, the waveguide (34) is a doped optical fibre, such as an Erbium-Ytterbium (Er-Yb) doped fibre. Light of the first (set) / second (reset) wavelengths excites or de-excites respectively the dopant ions in the fibre thus tuning its transmission.

Abstract translation: 光学电路包括具有第一和第二透射状态的双稳态光波导（34）。 波导对于第二状态中的给定波长的光比在第一状态下更透射。 第一光源（11）和第二光源（21）分别发射第一和第二波长的光，并且在一端耦合到波导。 通过波导的第一波长的足够量的光的选择性透射“设置”波导，使其从第一波长切换到第二状态，而第二波长的足够量的光的透射“复位”波导 使其从第二个状态切换回第一个状态。 在波导的另一端布置感测或读取（“测试”）光源（36），以将传感光信号通过波导（34）沿与第一和第二波长的光相反的传播方向传输 。 该感测光源可以是由波导中的自发发射提供的外部光源或“内部”源。 传感器（38）被布置成检测通过波导（34）传输的感测光信号的量。 以这种方式，波导可以被设置为给定的传输状态，其可以通过测量发射的感测光信号的量在稍后的时间来确定。 因此，光电路呈现存储效应，并且可以用于产生诸如光锁存器或光学翻盖的全光双稳态逻辑电路。 通常，波导（34）是掺杂光纤，例如铒 - 镱（Er-Yb）掺杂光纤。 第一（设置）/第二（复位）波长的光分别激发或去激励光纤中的掺杂剂离子，从而调整其透射率。

Abstract: A photonic switch (30) may be formed using one of a selected group of non-linear optical materials. Each of the materials within this group has a refractive index that demonstrates a substantial peak as a function of wavelength. The photonic switch (30) includes a positive gain, and thus acts as a photonic transistor. In addition, a photonic switch (30) is formed so that a gate signal is applied in a direction that is substantially perpendicular to the direction of the input signal so that there is no effective contamination of the input signal by the gate signal affecting the output signal.

Abstract: The present invention relates to labels which are adhesively attached to the outside of a stack of packages or articles which packages or articles are combined on a pallet typically by a stretch wrapped film. Such stretch wrapped stacks are highly stable but due to the stretch in the film used for holding the stack together and depending on the compressibility of the packages or articles, the stack will shrink by a certain amount during further handing and shipment. Such stretch wrapped stacks are usually provided with labels, which have to allow the stretch wrapped stack to shrink and be deformed to a certain extent during handing and shipment. The present invention relates to labels, which are designed, to achieve a substantial improvement in stability after having been applied to a stretch wrapped stack of packages or articles.

Abstract: The invention relates to non-linear fibre and integrated optics, more specifically to fully optical switches and optical transistors and can be used for fibre-optical communication lines, integrated optical circuits etc. The inventive method consists in switching solitons in cubic non-linear tunnel-coupled optical waveguides (TCOW) by weak signal pulses or by the continuos radiation of a different carrier frequency. Said switching is carried out from one waveguide to another waveguide. Said invention makes it possible to convert (with a high amplification) a weak signal pulse modulation whose frequency does not correspond to a soliton-forming and soliton-propagating region and/or to fibre waveguide windows into a power soliton-sequence modulation on another required carrier frequency. In addition, a parasitic effect of short time and slow phase signal modifications and the influence of a phase of soliton input on a switching process are excluded.
