Abstract

A device (10) for sensing an acoustic signal is described. The device includes a flexible portion (14) including a laser active region (13) whose emitted wavelength varies according to a mechanical force acting on the flexible portion (14) and a flexible support member (24) operable to flex or bend according to the acoustic signal. The flexible portion (14) is coupled with the support member (24) so as to cause the flexible portion to flex or bend in accordance with the support member (24) thereby changing the emitted wavelength of the laser active region (13) of the flexible portion (14).
