| 英文摘要 | In a first broad aspect, the invention provides a light source. The light source includes a semiconductor laser for emitting laser light at a first frequency. The light source also includes an optical fibre that includes a fibre Bragg grating. The fibre Bragg grating is optically coupled to the semiconductor laser for receiving the laser light, reflecting a reflected portion of the laser light towards the laser and allowing the transmitted portion of the laser light to pass through the fibre Bragg grating. The fibre Bragg grating has a temperature-dependant reflection spectrum. A frequency converting optical element is optically coupled to the fibre Bragg grating for receiving the transmitted portion of the laser light and converting at least a fraction of the transmitted portion of the laser light into a converted light having a second frequency different from the first frequency. An output port is optically coupled to the frequency converting optical element for outputting the converted light. A temperature controller is thermally coupled to the fibre Bragg grating for modulating a temperature of the fibre Bragg grating so as to modulate the reflection spectrum. |
