“…[24][25][26][27][28][29] Furthermore, the presented structure geometry is suitable for large-area fabrication, 58,59 which makes it a promising candidate design for non-reciprocal coatings of optical elements, such as lenses, with active external control at specific wavelengths. In addition, the direct attachment onto optical fiber ends [60][61][62] or onto laser diodes could yield devices with extremely small volumes for a highly integrated environment.…”

“…These devices realize one-way light propagation to suppress parasitic feedback in a multitude of optical systems, including optical telecommunication networks [24][25][26] and laser systems. [27][28][29] In addition, systems with less restricted symmetry properties that exhibit asymmetric transmission of light (both in a reciprocal and non-reciprocal manner) have gained considerable attention recently. [30][31][32] In the applications mentioned above, there is a strong trend toward highly integrated, tunable devices that demand dramatically downsized Faraday rotators.…”

We experimentally demonstrate an ultra-thin plasmonic optical rotator in the visible regime that induces a polarization rotation that is continuously tunable and switchable by an external magnetic field. The rotator is a magneto-plasmonic hybrid structure consisting of a magneto-optical EuSe slab and a one-dimensional plasmonic gold grating. At low temperatures, EuSe possesses a large Verdet constant and exhibits Faraday rotation, which does not saturate over a regime of several Tesla. By combining these properties with plasmonic Faraday rotation enhancement, a large tuning range of the polarization rotation of up to 8.46 for a film thickness of 220 nm is achieved. Furthermore, through experiments and simulations, we demonstrate that the unique dispersion properties of the structure enable us to tailor the wavelengths of the tunable polarization rotation to arbitrary spectral positions within the transparency window of the magneto-optical slab. The demonstrated concept might lead to important, highly integrated, non-reciprocal, photonic devices for light modulation, optical isolation, and magnetic field optical sensing. The simple fabrication of EuSe nanostructures by physical vapor deposition opens the way for many potentially interesting magneto-plasmonic systems and three-dimensional magneto-optical metamaterials.

Abstract:We demonstrate that the bits of a CD-ROM can be read without a photodiode (PD). A commercial CD-ROM drive was used and left unmodified except a beam splitter was removed which would route the light to a PD. This allowed for the reflected light to be incident on the laser within the laser package itself. By monitoring fluctuations in the voltage across the laser diode (LD) under constant-current injection, it was possible to read and interpret the bits from a spinning CD-ROM.

“…The semiconductor lasers tend to generate excess intensity noise, so-called the optical feedback noise, which is induced by reinjection of the output light into the laser by reflection at the surface of connecting optical devices, as well as the quantum noise which is caused by intrinsic fluctuations on the electron and photon numbers [1], [2]. The optical feedback noise can be suppressed by superposition of the HF (High Frequency) current [3] or by utilization of the selfpulsation laser [4].…”

SUMMARYReduction of the intensity noise in semiconductor lasers is an important subject for the higher performance of an application. Simultaneous usage of the superposition of high frequency current and the electric negative feedback loop was proposed to suppress the noise for the higher power operation of semiconductor lasers. Effective noise reduction of more than 25 dB with 80 mW operation was experimentally demonstrated. key words: semiconductor laser, optical feedback noise, noise reduction, electric negative feedback, high frequency current superposition
