| 英文摘要 | An electromagnetic radiation emission apparatus comprises a laser 114 thermally coupled to a heating device 116, for example, an electrically resistive material. The apparatus includes a temperature sensor. The heating device heats a laser in response to a temperature being below a threshold of a predetermined parameter for example, a side mode suppression ratio (SMSR), or a wavelength of the laser. A method supporting a WDM channel using the apparatus is also claimed. There is a method where a laser is selected from a plurality of lasers to support a channel of coarse wavelength division mixing CWDM. The method uses a heated laser. The use of a heating device to increase the number of laser devices usable in a CWDM system is also claimed. The CWDM system may operate over a temperature range are -40 - 85{C. |
