We present a low-loss, compact, polarization insensitive 3-dB optical power-splitter for submicron silicon waveguides. The splitter is optimized over broad wavelength span ranging from 1300 to 1700 nm through finite difference time domain simulations. junction footprint only 1.8 × 1.3 ?m, which smaller than previously reported broadband multimode splitters. Furthermore, the demonstrated device ...

Two modes are being considered for a 50 on 50-GeV muon collider: one being a high-luminosity ring with broad momentum acceptance (dp/p of ∼ 0.12%, rms) and the other lower luminosity with narrow momentum acceptance (dp/p of ∼ 0.003%, rms), or Higgs Factory. To reach the design luminosities, the value of beta at collision in the two rings must be 4 cm and 14 cm, respectively. In addition, the bu...

To evaluate the physiological responses of chrysanthemum to silicon spray in non-stress conditions, this study was performed in two separate experiments (at 4 to 5 and 8 to 12-leaf stages) as a factorial randomized completely design with two factors: silicon source (in two levels: sodium silicate and calcium silicate) and the concentration of silicate at five levels (0, 50, 100, 150 and 200 mg ...

Bawang merah (Allium ascalonicum) merupakan salah satu komoditas sayuran yang memiliki nilai ekonomis tinggi, baik ditinjau dari sisi pemenuhan konsumsi nasional maupun sumber penghasilan petani. Lahan pertanian sempit akibat pembangunan infrastruktur telah menjadi permasalahan berakibat pada penurunan produksi hasil khususnya sayuran. Usaha untuk mengatasi hal tersebut dengan sistem budidaya h...

the effect of different ratio of vermicompost (0, 10, 20, 30, 40 & 50 %) in two type of substrate (coco peat and coco peat-perlite (50:50 v:v)) on growth characteristics of gooseberry (physalis peruviana l.) seedling was investigated in research greenhouse of university of tehran, in 2013. a factorial experiment based on completely randomized design with four replications was carried out. crite...

In order to evaluate the different growing media and nitrogen fertilizer (urea) on some morphological traits of Spathiphyllum plant, an experiment was carried out in split plot arrangement based on completely randomized design in three replications in greenhouse conditions in 2018. The main plot consisted of different growing media including T1: Leaf-mold, T2: Vermicompost and T3: A mi...
