Characterization of Power-to-Phase Conversion in High-Speed P-I-N Photodiodes
Fluctuations of the optical power incident on a photodiode can be converted
into phase fluctuations of the resulting electronic signal due to nonlinear
saturation in the semiconductor. This impacts overall timing stability (phase
noise) of microwave signals generated from a photodetected optical pulse train.
In this paper, we describe and utilize techniques to characterize this
conversion of amplitude noise to phase noise for several high-speed (>10 GHz)
InGaAs P-I-N photodiodes operated at 900 nm. We focus on the impact of this
effect on the photonic generation of low phase noise 10 GHz microwave signals
and show that a combination of low laser amplitude noise, appropriate
photodiode design, and optimum average photocurrent is required to achieve
phase noise at or below -100 dBc/Hz at 1 Hz offset a 10 GHz carrier. In some
photodiodes we find specific photocurrents where the power-to-phase conversion
factor is observed to go to zero
Analisis Pemilihan Supplier Pupuk Npk Dengan Metode Analytical Hierarchy Process (Ahp)
Supplier selection is a chain in supply chain management. Supplier selection is one of the most important things in purchasing activity for the company. Companies should be selective in choosing suppliers because the right supplier selection will support the output of the company. This research was conducted at oil palm agribusiness company which will develop cooperative relationship with NPK fertilizer supplier. The purpose of this study is to select the best NPK fertilizer suppliers that meet the company's criteria. The criteria specified in choosing NPK fertilizer suppliers are cost, quality, delivery and service. While the suppliers who have worked with PT ABC Batam are suppliers X, supplier Y and supplier Z. This research uses AHP method assisted with expert choice v.11 software. From the assessment of the importance of criteria in the selection of suppliers, cost criteria get the highest weight of 0.452, then followed by the quality criteria with weight 0.234, service criteria with weight 0.163 and delivery criteria with weight 0.151. For supplier score starting from supplier X get highest weight 0.528, supplier Y with weight0.325 and supplier Z with weight 0.14
Analisis Kepuasan Pelanggan terhadap Kualitas Layanan Ojek Online (Wakjek) di Kota Batam
This study aims to measure the level of customer satisfaction with the quality of their online service (Wakjek) in Batam city. Primary data obtained by spreading the questionnaires to consumers using Random Sampling techniques with the total sample as many as 100 respondents. The data were analyzed using descriptive statistics. Consumer satisfaction against the dimensions of quality is described in the diagram of the Importance-Performance Analysis (IPA). IPA charts indicate that service dimension items scattered on the four quadrants, namely 15 items on A quadrant which is a top priority, 7 items in quadrant B that should be preserved, the next 7 items in quadrant C which is a low priority, as well as 12 items in quadrant D is an item that is considered less important. Research results exposed that the satisfaction of services provided by taxi online Wakjek has shown the good results it can be seen from the level of conformity that is indicated by the variable Y i.e. satisfaction service. On the attributes of the performance of the average value of the variable Y indicates the number of attributes exists while 4.77 hopes the average value of the variable Y shows numbers 3.62. This means that service satisfaction felt by customers of their online Wakjek have been able to meet the expectations of their customers online Wakjek itself but there are still some items that must be repaire
