We demonstrate a novel (to the best of our knowledge) 40 GHz passively mode-locked AlGaInAs/InP 1:55 μm laser with a low divergence angle (12:7° × 26:3°), timing jitter of 1:2 ps (10 kHz-100 MHz), and a radio frequency linewidth of 25 kHz. © 2011 Optical Society of America.

We present an 80-GHz λ ∼ 1.55 μm passively colliding-pulse mode-locked laser based on a novel AlGaInAs/InP epitaxial structure, which consists of a strained 3-quantum-well active layer incorporated with a passive far-field reduction layer. The device generated 910 fs pulses with a state-of-art timing jitter value of 190 fs (4-80 MHz), while demonstrating a low divergence angle (12.7°×26.3°) with two fold butt coupling efficiency to a flat cleaved single mode fiber when compared with the conventional mode-locked laser. © 2011 by Astro Ltd., published exclusively by WILEY-VCH Verlag GmbH & Co.

The monolithic integration of four 10-GHz 1.55-μm AlGaInAs/InP mode-locked surface-etched distributed Bragg reflector lasers with a 4 × 1 multimode-interference optical combiner, a curved semiconductor optical amplifier, and electroabsorption modulator using relatively simple technologiessurface-etched distributed Bragg reflector and quantum-well intermixinghas been demonstrated. Our techniques have the advantage of eliminating crystal regrowth and antireflection coating processes that are required in traditional methods. The four channels can operate separately or simultaneously. They also can be synchronized at the same pulse repetition frequency by the injection mode-locked technique. © 2011 IEEE.

The 10-GHz passively mode-locked AlGaInAs/InP 1.55-μm extended cavity lasers integrated with optimized surface-etched distributed Bragg mirrors have been fabricated. A quantum-well intermixing process was used to provide low-absorption loss gratings with accurate wavelength control. The lasers produce 2.99-ps sech 2-pulses with a time-bandwidth product (TBP) of 0.51. © 2006 IEEE.

The 45-GHz passively mode-locked AlGaInAsInP 1.55-μ lasers integrated with surface-etched distributed Bragg mirrors have been fabricated. Quantum-well intermixing was used to provide low absorption loss gratings with accurate wavelength control. The lasers produce 3.6-ps Gaussian pulses with time-bandwidth product of 0.57. © 2006 IEEE.

We have fabricated 40-GHz passively mode-locked AlGaInAs-InP 1.55-μm lasers integrated with surface-etched distributed Bragg mirrors. Numerically optimized gratings provide low-scattering losses and accurate wavelength control. The lasers produce 4.46-ps Gaussian pulses with time-bandwidth product of 0.47. © 2006 IEEE.

The first demonstration of harmonic mode-locked operation from a monolithic semiconductor laser comprising a compound cavity formed by twin deeply etched intracavity reflectors based on 1.55-μm AlGaInAs strained quantum-well material is presented. Nearly transform-limited Gaussian pulses are generated at 160-GHz repetition rate with a 1.67-ps pulse duration. © 2010 IEEE.

We characterized the reflectivity and the modal discrimination of intracavity reflectors (ICRs) with different numbers of slots and presented harmonic mode-locking operation of a monolithic semiconductor laser comprising a compound cavity formed by a single deeply etched slot ICR fabricated from 1:55 μm AlGaInAs strained quantum well material. Gaussian pulses were generated at a 161:8 GHz repetition rate with a pulse duration of 1:67 ps and a time-bandwidth product of 0.81. © 2010 Optical Society of America.

We know, we know… all you care about today are the new iPhones that Apple is getting ready to unveil. We still have a bit of time before Apple’s big event kicks off though, so why not enjoy some paid iPhone and iPad apps on sale for free while you’re waiting? We’ve got eight new iOS apps on sale for you today, and you’ll find a few more freebies in yesterday’s post as well. DON’T MISS: An idea that would make Apple’s iCloud a huge value for iPhone users These are paid iPhone and iPad apps that have been made available for free for a limited time by their developers. There is no way to tell how long they will be free. These sales could end an hour from now or a week from now — obviously, the only thing we can guarantee is that they were free at the time this post was written. If you click on a link and see a price listed next to an app instead of the word “get,” it is no longer free. The sale has ended. If you download the app, you will be charged. Black SMS protects your text messages with a password and hides them inside of black bubbles and fake replacement texts. A text that looks like it says “Hello” might actually say “Meet me at 6pm at the base of the Eiffel tower.” With Black SMS you don’t need to worry about others reading your private messages. The app can also password-protect your photo messages. The app uses a military-grade advanced encryption (AES-256) so messages are impossible to reveal without the correct password. What people are saying: – “Loved the idea! All my SMS’s are now safe and secure!” ⍟⍟⍟⍟⍟ – “It does what it says it does, potent, efficient, and very useful” ⍟⍟⍟⍟⍟ – “I really like using this. It’s easy to use and successfully prevents my gf from reading my texts everytime she borrows my phone she doesn’t even know that it’s a code she thinks I’m sending blank spaces” ⍟⍟⍟⍟⍟ – “This is so cool!
