  • Chirp Manipulation of Harmonically Mode-Locked Weak-Resonant-Cavity Colorless Laser Diode With External Fiber Ring

    The chirp manipulation of a colorless weak- resonant-cavity Fabry-Perot laser diode (WRC-FPLD) harmonically mode locking (HML) by 10-GHz direct modulation is demonstrated under the self-feedback control with an external single- or dual-fiber ring. With enlarging the self-feedback ratio through the fiber ring to 90%, the HML pulsewidth significantly shrinks to 14 ps for the colorless WRC-FPLD with ... View full abstract»

    In the first part of this paper, thermally induced polarization and phase distortions of a laser beam in cubic ceramics were calculated considering the specific features of photoelastic properties of 23 and m3 crystal classes. Here we use these quantities to calculate Strehl ratio and the integral of overlapping of the input and output beams both on passing one ceramic element as well as at the ou... View full abstract»

    The weak-resonant-cavity Fabry-Perot laser diode (WRC-FPLD) injection-locked by three master sources with different degrees of coherence and directly modulated by two different digital modulation formats is demonstrated. The injection master coherence shows impact on noise, bandwidth, and modulation performances of the slave WRC-FPLD transmitter. Using the highly coherent master, the injection-loc...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1184 KB) | HTML iconHTML

    This paper presents comprehensive studies on the stability of a semiconductor laser (SL) with external optical feedback. In particular, based on numerical computation on the Lang and Kobayashi equations, the stability limit under the condition of minimum linewidth is investigated, revealing how it is influenced by three major parameters associated with SL operation conditions, including the feedba...

    This paper reports the results of numerical and experimental investigations of the dynamics of an external-cavity diode laser device composed of a semiconductor laser and an external Bragg grating, which provides optical feedback. Due to the influence of the feedback, this system can operate in different dynamic regimes. The traveling-wave model is used for simulations and analysis of the nonlinea... View full abstract»

  • Optimization of an Asymmetric DFB Laser Used as All-Optical Flip-Flop

    We have numerically optimized the speed of an all-optical flip-flop based on an antireflection-coated λ/4 phaseshifted distributed feedback (DFB) laser. Numerical results show that by engineering the grating of the DFB laser and making the coupling coefficient asymmetrical, fall times reduce by a factor of 2 compared with a standard laser design. It is also shown that the confinement factor... View full abstract»

  • Improving the Vertical Light Extraction Efficiency of GaN-Based Thin-Film Flip-Chip LED With Double Embedded Photonic Crystals

    The vertical light-extraction efficiency (LEE) of the thin-film flip-chip light-emitting diodes with the embedded photonic crystal (PhC) is investigated using the finite-difference time-domain method. This paper systematically analyzes the dependence of the vertical LEE on the vertical structure and the embedded PhC parameters. It is found that the introduction of the p-side embedded PhC and n-sid... View full abstract»

  • An Optical Mode-Matching Method With Improved Accuracy and Efficiency

    Two fundamental principles of the mode-matching method-mode orthogonality and tangential field continuity conditions have been revisited in depth. With a finite number of modes employed in the conventional method, the tangential field continuity condition at the waveguide-discontinuity interface fails leading to a field mismatch error. We propose an alternate, superior mode-matching method impleme... View full abstract»

  • Subwavelength Line Imaging Using Plasmonic Waveguides

    We investigate the subwavelength imaging capacity of a 2-D fanned-out plasmonic waveguide array, formed by air channels surrounded by gold metal layers for operation at near-infrared wavelengths, via finite-element simulations. High resolution is achieved on one side of the device by tapering down the channel width, while simultaneously maintaining propagation losses of a few decibels. On the othe... View full abstract»

  • Thermal Noise-Limited Fiber-Optic Sensing at Infrasonic Frequencies

    The fundamental thermal noise in fiber-optic sensors remains to be an interesting research topic. In particular, its spectral behavior in the infrasonic frequency range has yet to be observed experimentally. In this paper, we assess the feasibility of probing the thermal noise floor at infrasonic frequencies with two sensor configurations: 1) fiber Fabry-Perot strain sensors and 2) Mach-Zehnder-Fa...
