理论上已经表明，通过耦合光程随温度减小的外腔，可以将半导体激光器振荡波长的温度系数降至零。这里描述了两种类型的温度补偿耦合腔 (TC3) 二极管激光器及其在稳态下计算的特性。在此类器件中，多腔引起的干扰效应预计会导致不稳定的跳模行为，但发现可以通过选择足够的外腔长度来解决。
It has been shown theoretically that the temperature coefficient of the oscillation wavelength in semiconductor lasers can be reduced to zero by coupling an external cavity whose optical length decreases with temperature. Here are described two types of temperature compensated coupled cavity (TC3) diode lasers and their properties calculated in the steady state. In such devices an interference effect due to multi-cavities is expected to cause unstable mode hopping behaviour, but it was found to be settled by choosing an adequate external cavity length.
