    摘要: A plurality of active gain material (93) is disposed in an active interface portion (44) of a dielectric band-gap cladding confinement region (22) adjacent to a dielectric core (12) of a photonic band-gap crystal fiber (20), wherein during operation, the plurality of active gain material (93) absorbs the pump energy and stores the pump energy as a potential energy storage for stimulation by EM energy in a second guided mode at a second frequency in a second range of frequencies for overlapping with the first guided mode of the core (12) such that the surface defined by an interface between the photonic band-gap cladding (22) and the dielectric core (12) that supports at least one surface mode propagating at that interface (44) overlaps the active interface portion of the dielectric cladding confinement region and a state associated with the dielectric core (12).

    摘要: Non-linear effects in an optical fiber used for communicating AM signals at high power levels are reduced by increasing the linewidth of the pump laser output signal. The linewidth can be increased by optically broadening the laser output signal by driving an optical angle modulator with broadband electrical noise. The optical signal is then externally modulated with an AM information signal for transmission over an optical link fiber. The optical modulation can be provided using either an FM or PM optical modulator. A desired linewidth can be provided by controlling the optical modulation index during the optical modulation step and/or by controlling the bandwidth of the noise source. Other techniques for broadening a laser output signal, including modulating the signal by a periodic function such as a sine wave, or injecting spontaneous emissions into the laser cavity, are also disclosed.

    摘要: According to one aspect, the invention relates to a device comprising an optical fibre having a high Brillouin threshold, said device including an optical fibre (101) suitable for propagating a high-power optical signal beam, means (11) for coupling a signal beam to an entrance end of the optical fibre (101) and a tubular structure (10) comprising at least one first tube (103) and at least one first adhesive material (102). According to the present description, at least one portion of the optical fibre is immobilized in the tubular structure (10) by means of the first adhesive material (102), which adheres both to the internal surface of the first tube (103) and to the external surface of the optical fibre (101). Furthermore, at room temperature and with no other external stresses on the device, the immobilized portion of the optical fibre (101) is maintained in a compressive state by the tubular structure, the compressive state being such that the relative deformation of the optical fibre is negative or zero in its portion immobilized in the tubular structure, the maximum value of the relative deformation of the immobilized portion of the optical fibre being higher in absolute value than 0.3%.
