احسان دانشؔ

احسان دانش
کچھ عرصہ سے اس برصغیر کی اردو شاعری کے آسمان پر سیاہ بادل برابر چھائے ہوئے ہیں، فراق گورکھپوری اور جوش ملیح آبادی کے بعد احسان دانش، حفیظ جالندھری اور اب نشور واحدی اﷲ کو پیارے ہوئے۔
ان کی رحلت سے اردو شعر و ادب کے قصر کی رنگارنگی میں بڑی کمی پیدا ہوگئی ہے، احسان دانش نے اپنی زندگی ایک پریشان حال مزدور کی حیثیت سے شروع کی، لیکن اپنی وفات سے پہلے اردو شاعری کے ایک تاجدار تسلیم کرلیے گئے تھے، ۱۹۴۷؁ء سے پہلے وہ اعظم گڑھ کے مشاعروں میں برابر آتے رہے، اس وقت تک ان کے کلام کے مجموعوں میں نفیر فطرت، جادہ نو، چراغاں، درد زندگی، نوائے کارگر، آتش خاموش حدیث ادب اور گورستان وغیرہ چھپ چکے تھے، مشاعرہ کے اسٹیج پر آتے تو ان کے چہرہ سے ان کی زندگی کی سادگی اور پریشانی ظاہر ہوتی، مگر کلام سناتے تو ان کے خیالات کی پرکاری اور رعنائی سے سامعین متاثر ہوکر محسوس کرتے کہ وہ اپنی شاعری میں جادو نو پر چل رہے ہیں، غزلیں سناتے تو تغزل کا چراغاں کرکے درد زندگی کے راز پنہاں کو عیاں کرتے، ان کی زندگی زیادہ تر پریشانیوں میں گزری، مگر وہ آتش خاموش بن کر ایک شاعر کا حق ادا کرتے رہے، اسی لیے ان کی سخنوری نوائے کارگر اور حدیث ادب بنی رہی، ان کی مشق سخن کی کہانی ان ہی کی زبانی یہ ہے کہ جب ان پر جذبہ شاعری طاری ہوتا وہ اپنی روح میں التہاب پاتے اور جب شعر سپرد قلم کردیتے تو محسوس کرتے کہ الفاظ میں، کاغذ پر، دائروں، لفظوں، مرکزوں اور پیوندوں کے نیچے ان کی روح دبتی چلی جارہی ہے، اور جب کوئی نظم پایہ تکمیل کو پہنچ جاتی تو اپنی روح کو سبک اور آرام طلب پاتے، پھر وہ میٹھی نیند...

ظاہری و باطنی صفائی اور مسلم معاشرے کاتعامل سيرت طيبہ کی روشنی ميں

Islam is a belief that prefers purity who introduces cleanliness from birth to demise. In the faith of Islam, there are orders for cleanliness, from cleansing the human body to the lane, the community, and the whole nation. Even the fact that all human deeds of worship are subject to ablution emphasizes the significance of cleanliness. Cleanliness is a commendation of Allah and the Sunnah of the Holy Prophet (S.A.W). Cleanliness is the nourishment of spirituality. Islam is theology in qualities. All the codes and prerequisites of exact nature are present in Islam. Islam has stressed cleanliness. It has instructed us to embrace both outer and inner cleanliness. Because the external influences the interior. Physical soundness is obtained, which makes it effortless to acquire internal cleanliness. When the inner self is also cleansed, an individual becomes a servant of Allah, freed from spiritual contaminants and impurities.

Photonic Generation of Width Tunable Uwb Pulses

Ultra-wideband (UWB) is a cutting edge, short range and huge bit rate wireless communication technique which provides communication services at Gbps data rates per user. The developing attraction for UWB is primarily due to its various interesting characteristics, such as reduced power emission, resilience to fading, little probability of interception, conformance with other wireless technologies and potential of supporting cost-efficient Gbps transmission to user ends. Owing to low power spectral density (PSD), the transmission distance is restricted from few meters to tens of meters. UWB over fiber (UWBoF) is a recent technique used to extend the range of UWB wireless transmission and also integrates the UWB services with fixed wired or wireless communication networks. Generally, this dissertation proposes various simple, efficient and novel all-optical techniques of UWB signal generation and transmission over single mode fiber (SMF), multimode fiber (MMF) and free space optics (FSO) link in order to effectively utilize the imposed Federal Communication Commission (FCC) mask. The proposed schemes are cost efficient and promising the seamless delivery of high data rate signals to user ends. In addition to UWB signal generation, a novel all-optical 2R (re-shaping and re-amplification) regeneration and continuous wave (CW) to pulsed signal wavelength conversion scheme is also presented which can be used to extend the range of UWBoF access network apart from its core function of optical signal re-shaping and reamplification. In particular, all-optical regenerative technique of width tunable UWB signal generation operating at 5 Gbps has been proposed and simulated where UWB mono-cycle pulses are generated by employing the nonlinearity of highly nonlinear fiber (HNLF) and semiconductor optical amplifier (SOA) based nonlinear mediums. Width tuning of generated UWB mono-cycle pulses is achieved with all-optical means. The regeneraix tive property of the proposed technique is verified by comparing with optical delay line (ODL) based UWB signal generation scheme. A simple and cost efficient scheme of UWB signal generation in optical domain has been proposed where UWB mono-cycle pulses are generated by exercising the nonlinearity between two linearly polarized (LP) modes in a SOA. The proposed bi-directional architecture promises the delivery of 2 Gbps data over MMF for down-link (DL) and up-link (UL) transmissions. Cost efficiency is achieved by employing direct modulation and carrier re-use techniques. This dissertation also explores the possibility of all-optical generation and transmission of UWB signals over FSO link. Therefore, a cost efficient architecture for generation and transmission of multiple UWB signals using all-optical technique over FSO link has also been presented based on Gamma-Gamma (GG) channel model which is employed between central unit (CU) and remotely distributed multiple radio access units (RAUs). The cost efficiency with added advantage of data transmission at higher data rates have been achieved by reducing the deployment cost by using FSO link instead of optical fiber and generating multiple coherent optical carriers by direct modulation of a single CW laser for data transmission. Finally, a novel all-optical 2R regenerator and CW to pulsed signal wavelength converter operating at 10 Gbps has been proposed which performs re-shaping and reamplification functions as well as wavelength conversion by inducing nonlinear chirp over CW probe by data modulated optical pulsed signal in HNLF and offset filtering. After inclusion of this 2R regenerator, the range of UWBoF access network can be extended beyond 40 km.
