Integers with no large prime factors [PDF]

Acta Arithmetica, 1995
For real numbers \(x,y\geq 2\), let \(\Psi (x,y)\) denote the number of integers not exceeding \(x\) all of whose prime factors do not exceed \(y\), and let \(\Psi_ q (x,y)\) denote the number of such integers that are also coprime to \(q\). Also let \(\omega (n)\) denote the number of distinct prime factors of \(n\) and let \(q_ y\) denote the product

High‐Resolution On‐Chip Digitally Tunable Spectrometer Based on Double‐Cascaded Ring Resonators

Advanced Photonics Research, EarlyView.
An integrated spectrometer is here presented, based on two cascaded ring resonators covered with a phase change material. The Vernier architecture is implemented allowing for a digital scan of wavelengths. Resolution smaller than 0.1 nm can be achieved, together with a footprint ≈0.03 mm2 and a bandwidth of the order of tens of nanometers.

Realizing Multispectral Fabry–Perot Structural Color Filters Based on Optical Nanostructures on a Complementary Metal Oxide Semiconductor Chip

Advanced Photonics Research, EarlyView.
A new paradigm for the implementation of Fabry–Perot color filters, which may be fabricated using complementary metal oxide semiconductor‐processing with significantly fewer process steps than the state of the art is demonstrated. It is streamlining and economizing the manufacturing process associated with commercial products incorporating color ...

Specialized integer factorization [PDF]

, 1998
Vanstone and Zuccherato [3] propose a cryptographic system based on an elliptic curve modulo a composite number. We show that the composite numbers so constructed are easily factored, rendering the system insecure.

High‐Isolation LCoS‐Based Optical Switch with Phase Hologram Parameter Optimization

Advanced Photonics Research, EarlyView.
A 1 × 9 liquid crystal on silicon (LCoS)‐based optical switch is experimentally demonstrated, revealing that the worst‐case port isolation exceeds 37 dB within the wavelength range of 1460–1540 nm. This work offers an alternative route for the development of optical switches with a large number of ports and high isolation, applicable to large‐capacity ...
