Abstract: A monolithic optoelectronic device has a spot-size converter optically connected to a waveguide. The overclad extending over the core of the waveguide is thinner and more highly doped that the overclad of the spot-size converter. This structure can be made by applying a process of selective etching and enhanced regrowth to create selective regions of the overclad of different thickness or doping.

Abstract: A monolithically integrated electroabsorption modulated laser having a ridge waveguide structure, has lateral ion implantation. The integrated device has a laser section and a modulator section. The modulator section has ion implanted regions adjacent to the waveguide ridge. The implanted regions penetrate through the top cladding layer to reduce capacitance within the intrinsic active core of the reverse biased modulator and allow a shallow etched ridge waveguide structure to be used for the modulator. The device provides good optical coupling, efficient manufacturing, and good high power performance.

Abstract: A Mach-Zehnder modulator has an optical splitting element splitting an input optical signal into two optical signals that are conveyed by two optical waveguide arms, and an optical combining element combining the two optical signals into an output optical signal. Two traveling wave electrodes (TWEs) carry an electrical modulation signal to induce a change in phase of these two optical signals, and include a number of pairs of modulation electrodes positioned adjacent to the waveguide arms. At least some of the electrodes in one waveguide arm have a different shape (e.g., length or width) than the electrodes in the other waveguide arm to alter the effectiveness of the electrodes in inducing a phase change in the two optical signals.

Abstract: An opto-electronic device comprises a waveguide along which light may propagate and an electrode associated with the waveguide and arranged to apply a variable electric field thereto. The waveguide includes one or more active regions in which variations in the electric field applied by the electrode to the waveguide cause variations in absorption of the light, and one or more passive regions in which variations in the electric field applied by the electrode to the waveguide cause substantially no variations in any absorption of the light. Relative proportions of the waveguide that comprise the active and passive regions vary along at least part of the length of the waveguide.

Abstract: A method for operating an optical system may include selecting a band gap energy level for an optical waveguide in an electro-optic modulator. The band gap energy level may correspond to a predetermined phase shift efficiency of a waveguide electrode coupled to the optical waveguide. The method may further include generating, across a conductive plane in the electro-optic modulator, a differential voltage that produces a predetermined temperature in a waveguide core of the optical waveguide. The predetermined temperature may correspond to the band gap energy level selected for the optical waveguide. The method may further include transmitting, through the optical waveguide and with a modulating voltage applied by the waveguide electrode, an optical wave to an optical wave combiner. The modulating voltage may produce an amount of phase shift in the optical wave at the predetermined phase shift efficiency.

Abstract: A Mach-Zehnder Modulator (MZM) pulse generator is provided having an increased power output. Power carved from the output signal in creating the pulses is recycled back to the input of the pulse generator via a feedback arm. Careful design of the length of the feedback arm such that a feedback signal has a propagation time of (2n+1)T/2 to complete one loop (n being a non-negative integer and T being the pulse period) allows a 50% duty cycle to be obtained using a driving frequency of only one half of the pulse frequency.

Abstract: An optical device comprises a semiconductor structure including first and second ridge waveguides, each waveguide comprising a ridge extending across a surface of the semiconductor structure. The ridge of the first waveguide has a first height above a first region of the surface, and the ridge of the second waveguide has a second, greater, height above a second region of the surface. The semiconductor structure includes a multimode interference (MMI) region situated between the first and second ridge waveguides, which provides a transition between them. At least a part of the MMI region is tapered in width and/or at least a part of the first and/or second ridge waveguide is tapered in width in a direction extending away from the MMI region.

Abstract: An integrated optical loop mirror has an optical coupler and an optical waveguide loop formed on a semiconductor substrate such that the waveguide connects two output ports of the coupler. Optical signals entering the input port of the coupler are directed around the waveguide loop and back to the input port, the device thereby provides an optical reflection or mirror function on a substrate. The integrated optical loop mirror is easily manufactured to provide accurate control of phase and magnitude of reflections and can be configured to provide wavelength dependent or independent reflections. It allows for placement flexibility, unlike cleaved facets which are restricted to chip edges. Other suitable substrates include glass and lithium niobate (LiNbO3). It can be constructed using various types of couplers and waveguides including photonic crystals. It is well suited to monolithic integrated optical designs incorporating lasers, such as distributed feedback (DFB) lasers, semiconductor optical amplifiers (SOA), integrated optical taps and Mach-Zehnder interferometers.
