According to the method, the spatial and spectral coupling of the single mode optical output of the master laser and a targed mode of the multimode optical resonator of the VCSEL slave laser are controlled to progress from a relatively mode-matched spatial and spectral coupling to a relatively mismatched spatial and spectral coupling to facilitate optically injected mode locking in the laser source. Further, a laser source is provided comprising a single mode master laser and a multimode VCSEL slave laser. The single mode master laser comprises a wavelength tuning element (60) and a spatial tuning element (15) that facilitate optically injected mode locking in the laser source spectrally mismatched optical seeding results in an enhanced modulation bandwidth of the VCSEL slave laser.

    Abstract: A transmission mechanism for transmitting an electrical signal from the output stage of an electro-optic transducer driver to an electro-optic transducer. The transmission mechanism includes the electro-optic transducer, the electro-optic transducer driver and a termination resistor. A first node of the termination resistor is coupled to the first differential input terminal of the electro-optic transducer. A second node of the termination resistor is coupled to the first output node of the electro-optic transducer driver. In addition, a second differential input terminal of the electro-optic transducer is coupled to a second output node of the electro-optic transducer driver. Such connections provide for a first DC path from the first differential input terminal of the electro-optic transducer to the second electro-optic transducer driver output node and a second DC path from the first node of the termination resistor to first electro-optic transducer driver output node.

    Abstract: A fast current-controlled polarization switching VCSEL with two independent intra­cavity p-contact electrodes and two independent intra-cavity n-contact electrodes positioned along the four sides of the symmetric aperture such that there are two independent p- and n- contact pairs placed on opposite sides of the aperture in a non-overlapping configuration. The anisotropy resulting from the unidirectional current flow causes the light output to be polarized perpendicular to the direction of current flow. A VCSEL driver circuit switches the polarization state of the output light by using the two orthogonal pairs of non-overlapping intra-cavity contacted electrodes to change the direction of current flow into the VCSEL aperture by 90 degrees.

    Abstract: An RF-lightwave transmitter (10) performs successive conversions of an information-bearing input signal in order to generate an output signal suitable for transmission in a wireless communications system. The transmitter (10) includes a high-efficiency FM laser (22) connected to a FM discriminator (24). In operation, the laser (22) converts an RF signal into a frequency-modulated optical signal, and the discriminator (24) converts this signal into an amplitude-modulated optical signal. The discriminator (24) performs its conversion using a high slope-efficiency linear transfer function which ensures that the AM optical signal varies in accordance with a desired operational performance.
