چکیده
We report on the generation and transmission of a millimeter-wave (MMW) signal with frequency 28 GHz by employing an InAs/InP quantum-dash dual-wavelength laser diode (QD-DWL) emitting in ~1610 nm extended L-band window. The self-injection locking (SIL) technique has been engaged to improve linewidth reduce noise optical tone. Besides, 2 Gbits/s quadrature phase-shift keying (QPSK)-modulated 28-GHz MMW beat tone over hybrid 20-km radio-over-fiber combined 5-m radio-over-free-space-optics up 6-m radio wireless link demonstrated. Moreover, comparing proposed QD-DWL commercial showcased similar performance characteristics, making candidate source for applications.

متن کاملBroadband Emission in Quantum-Dash Semiconductor Laser
A new type of semiconductor laser is studied, in which injected carriers in the active region are quantum mechanically confined in localized finite self-assembled wire-like quantumdash (Qdash) structures that are varied in sizes and compositions. Effects of such carrier distribution and quasi three-dimensional density of states contribute to a quasisupercontinuum interband lasing characteristic...

This paper presents a low loss and high selective lowpass filter which is implemented using suspended stripline (SSL) technology. The proposed structure is comprised of a 13th order generalized Chebyshev lowpass filter which enjoys integrated waveguide-to-SSL transitions. This filter is designed and fabricated to be used as lowpass channel of a U-band diplexer employed in frontend of a U-band d...
متن کاملMillimeter and Submillimeter Wave Applications
Many applications of millimeter and submillimeter wave systems have been suggested in the literature but, in general, they have not yet beea employed in practice to any significant degree. This report discusses the advantages and limitations of this frequency region and reviews the potential applications under the categories of radar, communications, radiometry and instrumentation. One of the p...
متن کاملNormal Incident Long Wave Infrared Quantum Dash Quantum Cascade Photodetector
We demonstrate a quantum dash quantum cascade photodetector (QDash-QCD) by incorporating self-assembled InAs quantum dashes into the active region of a long wave infrared QCD. Sensitive photoresponse to normal incident light at 10 μm was observed, which is attributed to the intersubband (ISB) transitions in the quantum well/quantum dash (QW/QDash) hybrid absorption region and the following tran...
