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.

Broadband 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...

Highly Selective Lowpass Filter with Wide Stopband in Suspended Stripline Technology for Millimeter-wave Diplexer Applications

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...

Normal 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...
