    Abstract: A distortion compensation circuit with frequency detection may be used with one or more non-linear elements, such as a laser, to compensate for frequency-dependent distortion generated by the non-linear element(s), for example, in broadband multichannel RF applications. Embodiments of the distortion compensation circuit may include a frequency detector circuit that detects changes in frequency loading conditions in the distortion compensation circuit such that distortion compensation may be adjusted to compensate for distortion under different frequency loading conditions. In a multichannel RF system with multiple channel operation modes, for example, the frequency detector circuit may detect changes in the frequency loading condition as a result of changing operation modes.

    Abstract: A surface-emitting laser, such as a VCSEL, for generating single-transverse mode laser light at a lasing wavelength, has a first mirror and a second mirror positioned so as to define a laser cavity therebetween, and a semiconductor active region disposed between the first and second mirrors for amplifying, by stimulated emission, light in the laser cavity at the lasing wavelength. An annular antiguide structure is disposed within the laser cavity and between the active region and one of the first and second mirrors, the annular antiguide structure comprising an antiguide material and having a central opening, the central opening comprising a second material having an index of refraction for light at the lasing wavelength smaller than that of the antiguide material, whereby the annular antiguide structure causes preferential antiguiding of higher order transverse lasing modes in the laser cavity.

    Abstract: The temperature at different locations along a multiplexed laser array may be monitored by sensing temperature at two locations within a transmitter optical subassembly (TOSA) package housing the laser array. The temperature at the two locations is used to determine a temperature tilt across the laser array. Estimated temperatures may then be determined at one or more other locations along the laser array from the temperature tilt. The estimated temperature(s) may then be used to adjust the temperature proximate the other locations, for example, for purposes of tuning lasers at those locations along the laser array to emit a desired channel wavelength. The TOSA package may be used in an optical transceiver in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).
