摘要： A gain medium is disposed between two mirrors to form a resonant cavity. The cavity length is selected so that the gain bandwidth of the gain medium is less than or substantially equal to the frequency separation of the cavity modes and such that a cavity mode frequency falls within the gain bandwidth. A nonlinear optical material is disposed either inside or outside the cavity to generate new laser wavelengths. The nonlinear optical material may be contained in a cavity which is resonant at the microchip laser frequency. Alternatively, the microchip laser may be tuned, for example thermally or by the application of a longitudinal or transverse stress, to the frequency of the resonant cavity. The laser is optically pumped by any appropriate source such as a semiconductor injection laser or laser array. Suitable gain media include Nd:YAG, Nd:GSGG and Nd pentaphosphate, and suitable non-linear optical material include MgO:LiNbO.sub.3 and KTP.

摘要： An optically active device comprising an optical fiber, a light source and a coupler is disclosed. The optical fiber has a core made of a silicate glass containing Rb and/or Cs oxide. The core is doped with Nd.sup.3+ as an active ion and transmits light at 1.3 .mu.m band. The light source generates excitation light at 0.8 .mu.m. The coupler directs the excitation light from the light source into the core of the optical fiber. A signal light or a spontaneous light at 1.3 .mu.m band which is transmitted in the core stimulates Nd.sup.3+ to emit light at 1.3 .mu.m band. As a result an optical function such as optical amplification can be effected at 1.3 .mu.m band.

摘要： The invention relates to lasers, and more particularly to solid state lasers such as neodymium on lithium niobate crystal lasers. The invention provides a structure with several juxtaposed optical waveguides (12) sufficiently close to each other laterally to be coupled laterally. In order to take into account the risks of inhomogeneity in the refractive indices or inaccuracies in the dimensions which would alter the distribution of the electromagnetic field of the propagation supermode in the coupled structure, it is proposed to act on the value of the index of propagation in each guide using an individual control (generally electrical). Because of the variation in index, individually controlled, phase differences in the laser wave between the different guides are produced and these phase differences react on the composition of the electromagnetic field defining the supermode. It is possible to go as far as modifying the directivity of the laser beam by this electrical control. The control is preferably achieved by electrodes (14) placed in the vicinity of each guide. The guides are made of an electro-optical material such as lithium niobate, and neodymium doping, for example, allows the laser effect to appear in the very interior of the guides.

摘要： The spectral-gain characteristics of an erbium-doped fibre amplifier have been tailored by incorporating a gain-shaping-filter within the amplifier. The filter is chosen to modify the natural gain spectrum of the amplifier so as to suppress the gain peak and thus flatten the overall spectral-gain profile. Because the amplifier is distributed, it is possible to insert one or more filters along the length of the fibre. It is shown that there are considerable advantages to locating the filter within the length of the amplifier, rather than at the end, which is the more obvious choice. Advantages are that the amplifier pump efficiency is almost unaffected and the output saturation power is similar to that of the unshaped amplifier. In addition, the flat spectral gain provides an amplifier ideally-suited for use at a number of signal wavelengths, as required for wavelength-division multiplexing (WDM). The invention therefore comprises both the concept of filtering to shape the gain response of the amplifier and the recognition that this can be achieved without penalty by careful location of one or more filters along the length of the amplifier.
摘要翻译： 掺铒光纤放大器的光谱增益特性已经通过在放大器内并入增益整形滤波器而被定制。 选择滤波器来修改放大器的自然增益谱，以抑制增益峰值，从而使整个频谱增益曲线变平。 因为放大器是分布式的，所以可以沿着光纤的长度插入一个或多个滤波器。 已经表明，将滤波器放置在放大器的长度内而不是结束处具有相当大的优点，这是更明显的选择。 优点是放大器泵效率几乎不受影响，输出饱和功率类似于未放大的放大器。 另外，平坦频谱增益提供了理想地适用于波分复用（WDM）所需的多个信号波长的放大器。 因此，本发明包括滤波以形成放大器的增益响应的概念以及通过沿放大器的长度仔细定位一个或多个滤波器可以实现这一点的识别。
